Question

As part of an exercise regimen, you walk 2 miles on an indoor track. Then you jog at twice your walking speed for another 2 miles. If the total time spent walking and jogging is 1 hour, find the walking and jogging rates.​

Answer 1

Answer:

Walking = 3 mph

Jogging = 6 mph

Step-by-step explanation:

time = distance/speed

walking + jogging = 1 hour

2/w + 2/(2w) = 1

use common denominator of 2w

4/(2w) + 2/(2w) = 1

6/(2w) = 1

reduce

3/w = 1

multiply both sides by w

3 = w

w = 3 mph

2w = 6 mph
