Question

oleg ran 8.8 miles in 1 hour 20 minutes. assuming he continues at a constant rate, how long will it take him to run any number of miles

Answer 1

V = d/t = 8.8 miles/[80/60] hours = 6.6 miles/hour

t = d/v = d/6.6

Answer: d/6.6, where d is the number of miles to run.

Answer 2

(6.62 × d) hours.

Explanation:

Oleg ran in 1 hour 20 minutes = 8.8 miles

1 hour 20 minutes = 1.33 hours

Formula of speed =
`(Distance)/(time)`

His average speed of running =
`(8.8)/(1.33)`

= 6.616 ≈ 6.62 miles/hour

Let the distance to run = d miles

it take him to run = (6.62 × d)

It will take (6.62 × d) hours to run.
