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**.
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**.
