Question

Lin ran 2 3/4 miles in 2/5 of an hour, Noah ran 8 2/3 miles in 4/3 of an hour. How long would it take Lin and Noah to run 1 mile at that rate?

Answer 1

Explanation:

Lin

Distance = 2 3/4 miles

Time = 2/5 hours

= distance / time

= 2 3/4 ÷ 2/5

= 11/4 × 5/2

= 55/8

= 6 7/8

It would take Lin 6 7/8 hour to run 1 mile at a constant rate

Noah

Distance = 8 2/3 miles

Time = 4/3 hour

= distance / time

= 8 2/3 ÷ 4/3

= 26/3 × 3/4

= 26/4

= 13/2

= 6 1/2

It would take Noah 6 1/2 hour to run 1 mile at a constant rate
