A train 108m long moving at a speend of 12m/s crosses a 112m long train coming from the oppositedirection in 11 secons qhat is the speed of the other train

Answer»

The SPEED of the other train is 8 m/sExplanation:GIVEN, the speed of the first train = 12 m/sLet the speed of the other train be v m/sThen speed of the first train relative to the second train = 12 + vThe first train covers total LENGTH of 108 + 112 = 220 m with speed 12 + v in 11 secondsTherefore, USING distance = speed × time220 = (12 + v) × 11or, 12 + v = 220/11 = 20or, v = 20 - 12 = 8Therefore, the speed of the other train is 8 m/sHope this answer is helpful.
