Find the distance traveled by a train moving at a speed
of 90 km/h, which takes 20% less time than a truck that covers 630 km at a speed of 70 km/h.Solution
Time taken by the truck = distance/speed = 630/70 = 9 hours Time taken by train = 80% of 9 = 7.2 hours Distance covered by train = 90×7.2 = 648 km Distance from A to B = 4320/2 = 2160 m = 2.16 km
