Question
A train running at the speed of 35 metre per second
crosses a bridge in 30 seconds. Another which is 130 metre shorter than the previous train crosses the same bridge at the speed of 40 metre per second. Find the time taken by the second train to cross the bridge?Solution
Let the length of the bridge be x m and that of the first train be y m (x+y)/35 = 30 x+y = 1050 Again (x+(y-130))/40 = t (x+y-130)/40 = t (1050-130)/40 = t 920/40 = t t = 23 seconds
