Answer» According to the GIVEN information TOTAL journey time = 19 hours The TRAIN has completed a 10 hour journey. The average speed of train is 100km/hr. So the total distance in 19 hours at a speed of 100km/h is = 19 (100) = 1900km The train has moved for 10 hours. So it has completed a disatnce in 10 hours = 10(100) = 1,000 km It had to wait due to the distribution of rail traffic. So the train completed the distance of 1,000km in 11 hours. NOW remaining distance = 1900 - 1000 = 900 km remaining times = 19 hours - 11 hours = 8 hours New Average Speed = Distance / Time = 900 / 8 = 112.5 km/h So the train had to move with a speed of 112.5 km/h to complete the journey in the same time (to cover the delay). |
