Thread: Distance Rate and Time

Can any one help me set this problem up?

Robin drove to work in the morning at an average speed of 45 mph. She returned home in the evening along the same route and averaged 30 mph/ If Robin spent 1 hour commuting to and from work, how many miles did she travel in the morning?

Since she traveled the same route, her distance was the same in the morning as it was in the evening going home.

Since d=rt, then t=d/r



Solve for d.
