**helper**, Tuesday, February 8, 2011 at 7:55pmD = RT (Distance = Rate x Time)

50 = rate going

T = time going

50T = distance going

45 = rate returning

T + .5 = time returning (30/60 = .5h)

45(T + .5) = distance returning

Distances are equal

50T = 45(T + .5)

50T = 45T + 22.5

5T = 22.5

T = 4.5 h

50T = distance going

50(4.5) = 225 miles

Answer as a decimal?
