Question

A car traveling at a certain speed will travel 76 feet per second. How many miles will the car travel in 3.1 hours if it maintains the same speed? Round to the nearest tenth (tenth in decimals).

Answer 1

$\sf \frac{76~ feet}{1~second} \times \frac{1~mile}{5280~feet} \times \frac{3600~seconds}{1~hour} = \frac{51.82~miles}{hour}$

51.82 miles in one hour, so 51.28 x 3 = 155.46 miles in 3 hours.

Your answer is 155.46 miles in 3 hours.
