Answer:

6mph

Step-by-step explanation:

In this question, we are asked to calculate the speed at which Carol jogs, given that she has a particular speed when she jogs greater than when she walks.

Firstly, we should understand that she is taking the same distance, whether she jogs or walks.

Now, letâ€™s say her jogging rate is x mph, this means that her walking rate would be (x – 4)mph. This is because her jogging rate is 4mph faster than her walking rate.

The total distance covered when jogging is thus 10/60 * x, while her total distance covered when walking would be 30/60 * (x-4)[we convert the time to hours]

We equate both since they are same distance:

x/6 = (x -4)/2

2x = 6(x – 4)

2x = 6x – 24

4x = 24

x = 6mph
