Question

Jill watched 72 minutes of a movie that is 149 minutes long.

What is the estimated number of minutes left if both numbers are rounded to the tens place?

What is the actual number of minutes left?

Answer 1

To find the estimated number of minutes left in the movie, we first round both 72 minutes (the amount Jill watched) and 149 minutes (the total length of the movie) to the nearest tens place.

- 72 rounds to 70.
- 149 rounds to 150.

Now we can calculate the estimated number of minutes left:

Estimated total movie length - Estimated minutes watched = Estimated minutes left

150 - 70 = 80 minutes

Now, to find the actual number of minutes left, we subtract the actual minutes watched from the total length of the movie:

Total movie length - Actual minutes watched = Actual minutes left

149 - 72 = 77 minutes

So, the estimated number of minutes left is 80 minutes, and the actual number of minutes left is 77 minutes.
