Problema Solution
Jennifer walks 6 miles in the same time she can job 11 miles. If Jennifer's jogging speed is 8mph faster than her walking speed, how fast can she walk?
Answer provided by our tutors
Let
v = Jennifer's walking speed
v + 8 = Jennifer's jogging speed
Since speed = distance/time follows time = distance/speed
Jennifer walks 6 miles in the same time she can jog 11 miles:
6/v = 11/(v + 8)
