Question

Determine the unit rate of a marathon runner who travels 5/2 miles in 1/4 hour

Answer 1

We can solve this to get the unit rate by doing this:-

5/2=1/4

5*4/2*1= 20/2

20/2=10

Or we could have done it this way:

5/2=2.5

2.5*4= 10

Either way we solve this....our answer will always be 10 miles per hour or 10 mph

Answer 2

(5/2 mile) ÷ (1/4 hour)

= (5/2) x (4/1) mph

= (20 / 2) = 10 mph
