Question

a lap around the track is 1/4 of a mile Cal ran six laps in 5 minutes and 30 seconds what was his average speed in miles per minute

Answer 1

Given:

Time= 5 minute 30 second

=5.5 minute

Distance= 6 laps

then:

`\begin{gathered} 1\text{ lap=}(1)/(4)mile \\ 6\text{ laps=}(6)/(4)miles \end{gathered}`

so speed in miles per minute is:

`\text{speed}=\frac{dis\tan ce\text{ }}{time}`

then speed of cal is:

`\begin{gathered} \text{speed}=((6)/(4))/(5.5) \\ =(6)/(22) \\ =0.2727 \end{gathered}`

The speed of cal is 0.2727 miles per minute
