As part of an exercise regimen you walk 9 miles on an indoor track. then you jog at three times your walking speed for another 9 miles. if the total time spent walking and jogging is 4 hours, find the walking and jogging rates

Rate of walking is and Rate of Jogging is .

Step-by-step explanation:

Given:

Total time = 4 hours

Jogging distance = 9 miles

walking distance = 9 miles

We need to find the walking and jogging rates.

Solution:

Let the walking rate be 'x'.

Now given that;

Jogging rate is 3 times faster than walking rate.

Jogging rate =

Now we know that;

Time is equal to distance divided by speed.

Time for walking =

Time for Jogging =

Now we know that:

Total time is equal to sum of Time for walking and Time for Jogging.

framing in equation form we get;

Rate of walking =

Rate of Jogging =

Hence Rate of walking is and Rate of Jogging is .
