Question

Doug entered a canoe race. He rowed 3 1/2 miles in 1/2 hours. What is his average speed in miles per hour?

Answer 1

3.5miles/0.5hour

=7miles/hr

Answer 2

7 mph (7 miles per hour)

Explanation:

3 1/2 = 3.5

1/2 = 0.5

Set up the ratio:

3.5/0.5 = x/1

Cross multiply:

3.5 × 1 = 0.5x

3.5 = 0.5x

3.5 ÷ 0.5 = x

7 = x
