A motor club has estimated that a 325 mile car trip will take 6 1/2 hours. What is the club assuming to be the average speed mil
In-s [12.5K]

<u>Answer: </u>

The average speed that the club is assuming is 50 miles per hour

<u>Solution: </u>

We know that Distance = Speed × Time.

Here it is given that distance is 325 miles and the time to cover 325 miles is 6_{2}^{1} hours which is equal to \frac{13}{2} hours.

Now to find the average speed mile per hour we use the formula

\begin{aligned} \text { Speed } &=\frac{\text { Distance }}{\text { time }} \\ &=\frac{325}{\frac{13}{2}} \\ &=\frac{325 \times 2}{13} \end{aligned}

By cancelling 325 by 13 we get 25

= 25 × 2  

= 50 miles per hour

Thus the average speed that the club is assuming is 50 miles per hour.
