Question from Ava:

Graham drove 42 1/3 Miles in 1 1/3 hours. How many miles did he drive in one hour?

Hi Ava,

Suppose Graham drove 75 miles in 3 hours going at a constant speed. Then in each hour he drove 25 miles so his rate was 15 miles/hour. That is he drove

\[\frac{75\mbox{ miles}}{3 \mbox{ hours}} = 3 \frac{\mbox{miles}}{\mbox{hours}}\]

What if he drove 42 1/3 miles in 1 1/3 hours?
