Question
If a boy runs at the speed of 20 km/hr and crosses a
bridge in 15 minutes, then what is the length of the bridge?Solution
Let us assume the length of the bridge be 'L' The speed of the boy = [20 × (5/18)] = (100/18) m/s The time = 15 minutes = (15 × 60) = 900 seconds L= [900 × (100/18)] = 5000 metres
