Question

. A train 150m long moving of 25m/s overtakes a
man moving at 5m/s in opposite direction. Find the
time taken by the train to cross the man.​

Answer 1

Answer:

Step-by-step explanation:

Let the speed of the train be v km/hr  

Relative speed of the train = (v + 35) km/hr = [(v + 35) x 5/18] m/sec  

∵ 150/5 = (v + 35) x (5/18)  

(30*18)/5=v+35

108=v+35

v=73 km/hr
