Aretha's trip to an art supply store took 1 1/6 hours. Her return trip took only 5/7 of the time of her trip to the store. How was long Aretha's return trip? What was Aretha's total driving time

Answer: 0.83 hrs; 2 hours

Given:

Aretha's trip to the store = 1 1/6 hours.

Aretha's return trip = 5/7 (1 1/6) hours

To find Aretha's return trip in hours

Let X = Aretha's return trip in hours

X=5/7 (1 1/6)

X = 5/7 (7/6)

X = 0.714286 (1.166667)

X = 0.833333

X=.83

To find Aretha's total driving time, add 1.17 and 0.83 = 2 hours
