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 mile per hour?

Respuesta :

Answer:

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

Solution:

We know that Distance = Speed × Time.

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

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

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

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.
