Question
Quantity I : The rate at which the train must run to
reduce the time to 30 minutes. A train takes 40 minutes for a journey if it runs at 72 km/hr. Quantity II : The speed of the train, Shailendra travelled 400 km by train and 300 km by taxi. It took him 4 hrs and 10 min. However, if he travels 360 km by train and 540 km by taxi, he takes 56 minutes more.Solution
Quantity I: Distance = 72 × 40/60 = 48 km Speed = 48/(30/60) = 96 km/hr Quantity II: Let the speed of train is x km/hr and speed of taxi is y km/hr 400/x + 300/y = 25/6 4/x + 3/y = 1/24 ……….. (1) 360/x + 540/y = 51/10 120/x + 180/y = 17/10 …………. (2) By solving 1 and 2, We get x = 150 km/hr and y = 200 km/hr so Quantity II = 150 km/hr Hence, Quantity I < Quantity II
