2. Lois rode her bike to visit a friend. She traveled at 10 mi/h. While she was there it began to rain. Her friend drove her home in a car traveling at 20 mi/h. Lois took 1.5 h longer to go to her friend's than to return home. How many hours did it take Lois to ride to her friend's house?

**DrBob222**, Tuesday, October 9, 2007 at 8:35pmdistance = rate x time

passenger train rate = 60 mi/hr

freight train rate = 40 mi/hr.

distance traveled by P = 60*t

distance traveled by F = 40*t

time for F is 1.5 hours longer than P so

F dist = 40(t+1.5) = P dist = 60*t

set distance = to each other

60*t=40(t+1.5)

solve for t = time for passenger train.

Then t+1.5 = tiome for freight train.

2/3(t+1.5)= T
