Explanation

Using the conversion 1 hour = 60 minutes, we multiply hours by 60 to get minutes, or divide minutes by 60 to get hours. The double number line shows: 2 hr = 120 min, 4 hr = 240 min, 7 hr = 420 min, 8 hr = 480 min, 9 hr = 540 min, 11 hr = 660 min, 12 hr = 720 min.

Solution Steps

  1. 1 hr = 60 min

  2. 2 hr = 2×602 \times 60 = 120 min

  3. 4 hr = 4×604 \times 60 = 240 min

  4. 7 hr = 7×607 \times 60 = 420 min

  5. 8 hr = 8×608 \times 60 = 480 min

  6. 9 hr = 9×609 \times 60 = 540 min

  7. 11 hr = 11×6011 \times 60 = 660 min

  8. 12 hr = 12×6012 \times 60 = 720 min
