Given:
Time= 5 minute 30 second
=5.5 minute
Distance= 6 laps
then:
[tex]\begin{gathered} 1\text{ lap=}\frac{1}{4}mile \\ 6\text{ laps=}\frac{6}{4}miles \end{gathered}[/tex]so speed in miles per minute is:
[tex]\text{speed}=\frac{dis\tan ce\text{ }}{time}[/tex]then speed of cal is:
[tex]\begin{gathered} \text{speed}=\frac{\frac{6}{4}}{5.5} \\ =\frac{6}{22} \\ =0.2727 \end{gathered}[/tex]The speed of cal is 0.2727 miles per minute
