Jesse jogs at a rate of 6 miles per hour. The next time she jogs, she increases her speed to 7 miles per hour. How long will it take her to jog 6 miles?

• Math -

First, Jesse covers 6 miles in 1 hour at 6 miles per hour (60 minutes).

If his new speed is 7 miles per hour:

Velocity= Distance/Time
Solve for Time(T):
TIME(T) =DISTANCE/VELOCITY...becomes:
T(hr)=(6 miles X 1HR)/7 miles
Miles cancel, leaves hour(T),therefore 6/7=.857hours
(.857 hours X 60 min)/hr=
