Question

Allen runs 8 miles in 3 hours at a steady pace.  how long does it take him to run 3 miles

Answer 1

It takes Allen 1 1/8 hours to run 3 miles.

Answer 2

`\begin{array}{ccc}8miles&-&3hours\\\\3miles&-&xhours\end{array}\\\\8x=3\cdot 3\\\\8x=9\ \ \ \ /:8\\\\x=(9)/(8)\\\\x=1(1)/(8)\ (h)`




`v=(8)/(3)\ mph\\\\s=3miles\\\\t=s:v\\\\t=3:(8)/(3)=3\cdot(3)/(8)=(3)/(1)\cdot(3)/(8)=(9)/(8)=1(1)/(8)\ (h)`
