How can I solve that problem

drek231 [11]

What do we know so far:

$2\frac{2}{3}laps$ in $\frac{4}{15}hour$ ⇒ $\frac{8}{3}laps$ in $\frac{4}{15}hour$

*we converted the number of laps into improper fractions

$2\frac{2}{3} = \frac{8}{3}$

We want to know the number of laps in an hour

⇒ so we must find the rate which ⇒ lap/hour

$lap/hour =\frac{8/3laps}{4/15hours} =\frac{8}{3}*\frac{15}{4} =\frac{8}{4} *\frac{15}{3} =2*5=10laps/hour$

So William can run ⇒ 10 laps in one hour

Hope that helps!
