11. A bus travelling at 42 km/h covers a distance in 5 h. How much time would it save if it increased its speed by 8 km/h?
Asked by rojesh.sahoo | 14 Feb, 2019, 10:01: AM
Expert Answer
Distance travelled = speed×time = 42×5 = 210 km
time taken if speed is 50 km/hr = 210/50 = 4hr 12 min
time saved = 5hr - 4hr 12 min = 48 min
