Problema Solution
How bad is the heavy traffic? You can jog 8 miles in the same time that it takes to travel 16 miles by car. If the car's rate is 7 miles per hour faster than your jogging rate, find the average rate of each.
Your jogging rate is _____miles per hour.
Answer provided by our tutors
Distance = Rate * Time
Time = Distance / Rate
8 / Jog Rate = 16 / Car Rate
call J = Jog Rate in mph
C = car rate in mph
8/J = 16/C ; J/8 = C/16 ; C = 2J
C = J + 7
2J = J + 7
J = 7 mph (jogging)
C = 7 + 7 = 14 mph (car)
