Question
A 200-meter long truck is traveling at a speed of 180
km/hr, and it takes 10 seconds to cross a toll plaza. Now, if another truck, which is 180 meters shorter than the toll plaza, attempts to cross the same toll plaza at a speed of 252 km/hr, how much time will it take to do so?Solution
ATQ, Let the length of the Toll plaza be 't' metres Speed of Truck = 180 × 5/18 = 50 m/s According to the question, (200 + t)/50 = 10 Or, t = 300 metres Length of the second Truck = 300 – 180 = 120 metres Speed of the Truck = 252 × (5/18) = 70 m/s Therefore, (300 + 120)/70 = 6 seconds
