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?

1 answer

To estimate the number of minutes left in the movie, we first round both the watched time and the total movie length to the nearest tens place.

  1. Round the watched time (72 minutes):

    • The nearest tens place to 72 is 70.

  2. Round the total movie length (149 minutes):

    • The nearest tens place to 149 is 150.

Next, we will calculate the estimated number of minutes left in the movie:

\[ \text{Estimated remaining time} = \text{Total movie length} - \text{Watched time} \] \[ \text{Estimated remaining time} = 150 - 70 = 80 \text{ minutes} \]

Therefore, the estimated number of minutes left in the movie is 80 minutes.
