Question

A bicycle is traveling at 21 miles per hour.How many feet will it cover in 15 seconds?Round your answer to the nearest tenth of a foot.Answer: __feet

Answer 1

`\begin{gathered} 1hour=3600secs \\ xhour=15secs \\ \\ \therefore x=(15secss*1hour)/(3600secs)=(15)/(3600)=(1)/(240)hr \end{gathered}`

The formula for distance is,

`distance=speed* time`

Therefore,
