Question
A train has to cover a distance of 135 km in 15 hours.
If it covers half journey in 3/5th time, then the speed of covering the remaining distance in the time left has to be:Solution
Speed = Distance/time = 135/15 = 9 km/hr According to the question, New time = 3/5 x 15 = 9 hrs New distance = 1/2 x 135 = 67.5 km Required speed = Distance left/Time left = 67.5/6 = 11.25 km/hr
