ICSE Class 7 Answered
A man walks at the speed of 4km/h. A train coming from behind him at the speed of 22km/h passes him in 30s. Find the length of the train
Asked by sandhyadwivedi0 | 19 Dec, 2018, 10:16: AM
Expert Answer
Speed = 22km/hr - 4km/hr = 20km/hr = 20 × 1000/3600 = 5.56s
Time = 30s
Distance = Speed × Time = 5.56 × 30 = 166.8m
Hence the length of the train is 166.8m.
