  1. 270Answer
  2. B
    290
  3. C
    245
  4. D
    450

Answer

The total duration of the time frame is 270 minutes.
The correct answer is found by multiplying the total number of hours (4.54.5) by the number of minutes in a single hour (6060). 4.5×60=2704.5 \times 60 = 270 minutes.

Step-by-Step Solution

1
Identify the conversion factor between hours and minutes.
11 hour =60= 60 minutes.
To convert a measurement in hours to minutes, you must multiply by 60.
2
Set up the multiplication for the total hours given.
4.5×604.5 \times 60
The team has 4.5 hours, and each hour contains 60 minutes.
3
Calculate the final product.
4.5×60=2704.5 \times 60 = 270 minutes.
This can also be calculated by splitting the time: 44 hours ×60=240\times 60 = 240 minutes, and 0.50.5 hours (half an hour) is 3030 minutes. 240+30=270240 + 30 = 270 minutes.
