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.

Step-by-step 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=}(R+W)/(H+H) \\ =(R+W)/(2H) \end{gathered}`
