A) 3 hrs 20 min  B) 4 hrs 20 min  C) 5 hrs 20 min  D) 6 hrs 20 min  E) 3 hrs 30 min
Let t be the usual time. If the usual rate is 1 unit, then the unusual rate is 5/6.   Balance by the distance,   1*t = (5/6)(t+40)   6t = 5(t+40)   Solve for t,   t = 200 minutes = 3 hrs 20 min   3 hrs 20 minNSWER:3 hrs 20 min
