Question
A train travels 240 km at the speed of 60 km/h and the
remaining distance at 80 km/h. If the total time taken by the train to cover the entire distance is 6 hours, find the total distance travelled by the train.Solution
Let the total distance travelled be x km. Time taken to cover the first 240 km = 240 / 60 = 4 hours. Time taken to cover the remaining distance = (x - 240) / 80 hours. The total time taken is 4 hours, so: 4 + (x - 240) / 80 = 6, (x - 240) / 80 = 2, x = 160 + 240 = 400 km Total distance = 400 km.
