rate = distance / time = (44 / 5 mi) / (4 / 3 hr) = 33 / 5 = 6.6 mph
time = distance / rate
to find the time for any distance , just divide by 6.6 mph
Half a mile ? 0 miles?
time = distance / rate
to find the time for any distance , just divide by 6.6 mph
= 1 1/3 hour
= 4/3 hour
since rate = distance/time
we have 8.8/(4/3) mph
= 8.8(3/4) mph
= 26.4/4 mph
= 6.6 mph
Scott just arrived at the same rate using different constants.
note that 8.8 = 88/10 = 44/5 <----- he used that in the numerator.
Now that we have the rate, just use
Time = distance/rate
to find the times for different distances
We know that Oleg ran 8.8 miles in 1 hour and 20 minutes. First, we need to convert 1 hour and 20 minutes to a single unit of time (either hours or minutes). Since there are 60 minutes in an hour, we can convert 1 hour and 20 minutes to 1.33 hours (1 hour + 20 minutes/60 minutes).
Next, we can find Oleg's running rate by dividing the distance he ran by the time it took him:
Running rate = Distance / Time
Running rate = 8.8 miles / 1.33 hours
Now, we can use this running rate to calculate the time it would take Oleg to run any number of miles.
1) Half a mile:
To find the time it would take Oleg to run half a mile, we divide the distance (0.5 miles) by the running rate:
Time = Distance / Running rate
Time = 0.5 miles / (8.8 miles / 1.33 hours)
Time = 0.5 / (8.8 / 1.33)
Time ≈ 0.075 hours or approximately 4.5 minutes
Therefore, it would take Oleg approximately 4.5 minutes to run half a mile.
2) 0 miles:
Since Oleg is not running any distance (0 miles), the time it would take him is zero.
Therefore, it would take Oleg no time to run 0 miles.
Keep in mind that these calculations assume Oleg continues to run at a constant rate.
