Question
A bus covers a certain distance without stopping at an
average speed of 50 km/h. But when it covers the distance intermittently. So its average speed is 40km/h. So tell me how much time does it stop on average per hour?Solution
Have given. Speed of bus without stopping = 50 km/h Intermittent speed of bus = 40 km/n Let the Distance is 200 Km Time taken to cover 200 km at the speed of 50Km/h = 4 Hours Time taken to cover 200 km at the speed of 40Km/h = 5 Hours Time interval (Time Difference) = 1 hours Running time: Stopping time = 4:1 Part of stopping time =Â
