Question

If a man walks W miles in H hours, and then R miles in the same length of time, what is his average rate for the entire trip?A. R+W/HB. 2(R+W)/HC. R+W/2HD. R-W/H

Answer 1

Given that a man walks W miles in H hours, and then R miles in the same length of time we asked to find his average rate for the entire trip.

Explanation

To do this we need to define what rate implies. Rate means a quantity, amount, or degree of something measured per unit of something

Case in point, we are measuring the distance covered with respect to time. The formula would be given as;

$\text{average rate = }\frac{Total\text{ distance covered in the journey}}{\text{Time taken to complete the journey}}$

The total distance is the sum of the number of miles walked and the time taken is the total time to complete the trip.

Therefore,

$\begin{gathered} \text{average rate=}\frac{R+W}{H+H} \\ =\frac{R+W}{2H} \end{gathered}$
