A mail truck traveled 102 miles in 3 1/2 hrs. The distance is the product of the rate and the time. To the nearest tenth, what was the average speed of the mail truck?

Total distance tarvelled= 102 miles

Total time taken =3.5 hrs

Speed is given by,

`\begin{gathered} \text{Speed}=\frac{Dis\tan ce}{\text{Time}} \\ \text{ =}(102)/(3.5)=29.14\text{ miles/hour} \end{gathered}`

To the nearest tenth the speed is 30 miles/hour.
