Rate of speed: 1.2 miles ÷ 8 minutes = 0.15 miles per minute

2 hr and 12 min = 60 + 60 + 12 = 132 minutes.

132 minutes x 0.15 miles / minute = 19.8 miles.

2 hr 12 min = 132 min

132 / 8 = 66 / 4 = 33 / 2

1.2 * 16.5 = 19.8 miles

2 hr 12 min = 132 min.

1.2/8 = x / 132 Cross mult.

8x = 158.4

x = 19.8 miles
