Question

A bicycle is traveling at 20 miles per hour. How many feet will it cover in 30 seconds? Round your answer to the nearest tenth of a foot.

Answer 1

`Distance = 880ft`

Explanation:

Given

`Speed = 20(miles)/(hour)`

`Time = 30\ seconds`

Required

Determine the distance

To answer this question, we make use of speed-distance relationship

`Speed = (Distance)/(Time)`

Make Distance the subject

`Distance = Speed * Time`

`Distance = 20 miles/hour * 30 seconds`

Convert seconds to hour

`Distance = 20 miles/hour * (30)/(3600) hour`

`Distance = 20 miles * (30)/(3600)`

`Distance = (20 miles * 30)/(3600)`

`Distance = (600\ miles)/(3600)`

`Distance = (1)/(6) miles`

Convert to foot

`Distance = (1)/(6) * 5280\ ft`

`Distance = (1* 5280\ ft)/(6)`

`Distance = (5280\ ft)/(6)`

`Distance = 880ft`
