Question
A train has to cover a distance of 240 km in 20 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 = 240/20 = 12 km/hr According to the question, New time = 3/5 x 20 = 12 hrs New distance = 1/2 x 240 = 120 km Required speed = Distance left/Time left = 120/8 = 15 km/hr
