Millie drives from home to the Fixit Garage at a rate of 30 mph. She leaves her car and rides a bus back home. The bus makes the trip at a rate of 20 mph. If her total travel time for the round trip is one hour, how many miles from the home is the Fixit Garage?

Speed =Distance travelled/ Time

Time =Distance travelled/ Speed

T = D / 30 The time it took her to drive to Fixit.

T = D / 20 The time it took her to ride the bus home.

D / 30 + D / 20 = 1 hour, solve for D,

D = 12 Miles from her house to Fixit.
