Question

Cesar runs 9 2/3feet in 15 minutes what is his speed?

Answer 1

To calculate Cesar's speed we need to divide the distance travelled by him by the elapsed time. On this case we have:

`\begin{gathered} v=(d)/(t) \\ v=(9(2)/(3))/(15) \\ v=(9+(2)/(3))/(15) \\ v=((29)/(3))/(15) \\ v=(29)/(3)\cdot(1)/(15) \\ v=(29)/(45)\text{ = }0.64\text{ miles per minute} \end{gathered}`

Cesar's speed is equal to 0.64 miles per minute or 29/45 miles per minute.
