The countdown for a spacecraft launch was halted at 12 hours, 9 minutes, 34 seconds before liftoff. The next stop occurred 1 hour, 24 minutes, 6 seconds before liftoff. How long was it from the first halt of the launch to the second halt of the launch?

Question

Select the correct answer.


Question 1 options:

10 hours, 35 minutes, 26 seconds

10 hours, 45 minutes, 28 seconds

11 hours, 18 minutes, 28 seconds

Answer 1

To find the duration between the first halt and the second halt, we need to subtract the time of the first halt from the time of the second halt.

The time of the first halt is 12 hours, 9 minutes, 34 seconds.

The time of the second halt is 1 hour, 24 minutes, 6 seconds.

To subtract these times, we start from the seconds and work our way up to the hours:

Seconds: 6 - 34 = -28 (We borrow 1 minute and add 60 seconds, so 6 - 34 + 60 = 32 seconds)

Minutes: 24 - 9 - 1 (borrowed) = 14 minutes

Hours: 1 - 12 = -11 (We borrow 1 hour and add 24 hours, so 1 - 12 + 24 = 13 hours)

Therefore, the duration between the first halt and the second halt is 13 hours, 14 minutes, 32 seconds.

Therefore, the correct answer is 11 hours, 14 minutes, 32 seconds.

B .10 hours, 45 minutes, 28 seconds

C .11 hours, 18 minutes, 28 seconds

Answer 3

To find the duration between the first halt and the second halt, we need to subtract the time of the first halt from the time of the second halt.

The time of the first halt is 12 hours, 9 minutes, 34 seconds.

The time of the second halt is 1 hour, 24 minutes, 6 seconds.

To subtract these times, we start from the seconds and work our way up to the hours:

Seconds: 6 - 34 = -28 (We borrow 1 minute and add 60 seconds, so -28 + 60 = 32 seconds)

Minutes: 24 - 9 - 1 (borrowed) = 14 minutes

Hours: 1 - 12 = -11 (We borrow 1 hour and add 24 hours, so -11 + 24 = 13 hours)

Therefore, the duration between the first halt and the second halt is 13 hours, 14 minutes, 32 seconds.

Therefore, the correct answer is 11 hours, 14 minutes, 32 seconds.

Answer 4

Alan begins working each day at 7:50 a.m. and finishes at 5:30 p.m. He takes a one-hour lunch break, which is not included in the amount of hours he works each day. How long does Alan work each day?

Select the correct answer.


Question 2 options:

9 hours 20 minutes

8 hours 40 minutes

9 hours 40 minutes

Answer 5

To find out how long Alan works each day, we need to subtract the duration of his lunch break from the total time from when he begins working to when he finishes.

Alan begins working at 7:50 a.m. and finishes at 5:30 p.m.

This totals to 9 hours and 40 minutes.

Since Alan takes a one-hour lunch break, we subtract 1 hour from the total time.

9 hours and 40 minutes - 1 hour = 8 hours and 40 minutes.

Therefore, Alan works for 8 hours and 40 minutes each day.

The correct answer is 8 hours 40 minutes.

Answer 6

Find the total.

Question 3 options:

14 hours, 54 minutes, 50 seconds

15 hours, 14 minutes, 30 seconds

15 hours, 4 minutes, 40 seconds

Answer 7

To find the total, we need to add the hours, minutes, and seconds separately.

Hours: 4 + 10 = 14 hours

Minutes: 5 + 59 = 64 minutes. Since there are 60 minutes in an hour, we carry over 1 hour and subtract 60 from the minutes. So 64 minutes - 60 minutes = 4 minutes.

Seconds: 11 + 29 = 40 seconds

Therefore, the total is 14 hours, 4 minutes, 40 seconds.

The correct answer is 14 hours, 4 minutes, 40 seconds.

Answer 9

To find the total, we need to add the hours and minutes separately.

Hours: 4 + 3 = 7 hours

Minutes: 51 + 16 = 67 minutes. Since there are 60 minutes in an hour, we carry over 1 hour and subtract 60 from the minutes. So 67 minutes - 60 minutes = 7 minutes.

Therefore, the total is 7 hours, 7 minutes.

The correct answer is 7 hours, 7 minutes.

Answer 10

4 hours 51 minutes

+ 3 hours 16 minutes

Answer 11

To find the sum of 4 hours 51 minutes and 3 hours 16 minutes, we add the hours and minutes separately.

Hours: 4 + 3 = 7 hours

Minutes: 51 + 16 = 67 minutes. Since there are 60 minutes in an hour, we carry over 1 hour and subtract 60 from the minutes. So 67 minutes - 60 minutes = 7 minutes.

Therefore, the total is 7 hours and 7 minutes.

The correct answer is 7 hours 7 minutes.

Answer 12

Cheryl is flying from Baltimore, Maryland, to her parents' home in Portland, Oregon. Her flight leaves Baltimore at 9:15 a.m. The non-stop flight lasts 6 hours. There is a 3-hour time difference between Baltimore and Portland, which subtracts 3 hours from the trip. What time will Cheryl arrive in Portland?

Answer 13

Cheryl's flight leaves Baltimore at 9:15 a.m. and lasts for 6 hours.
To find the arrival time in Portland, we need to add the duration of the flight and the time difference to the departure time.

So, 9:15 a.m. + 6 hours = 3:15 p.m.

There is a 3-hour time difference between Baltimore and Portland which needs to be subtracted.

3:15 p.m. - 3 hours = 12:15 p.m.

Therefore, Cheryl will arrive in Portland at 12:15 p.m.
