Sir in first question distance covered by train in 15 min= 40*15*60=36000m which is 36km and man will cover t=36/4=9hr...... please Clear my confusion

Speed of train is 40km/hr not 40m/s. So, the distance will be 40*15/60
sir in the first question as it is mentioned that man running in the direction of train so my doubt is that isn't the man running towards the train. can the questions be solved as opposite direction case. as it will give the ans as 2 which is also given in the option
DR
sir please the explain the last question in 27th lec. as how relative speed of A is calculated by adding while the case is in same direction
Rs
in last question it should be 500/8+12

ya .... same query

It should be 500/(12+12), as rel speed of A is 10+2, while the rel speed of B is 15-3. In the question speed of B is given as 3 m/s, but sir considered it as 2 m/s. Maybe it's a print mistake.
Rs
bcos in same direct Speed is subtracted
1. TIME, SPEED AND DISTANCE TRAIN-4 Practice Questions

2. A train of length 300m crosses a man runningTwo trains A and B pass through a station on two with the speed 4 km/hr in the direction of trainparallel tracks without stopping at the station on in 30 sec. If after crossing man train reached two different platform. The platform P2 passed by next station exactly after 15 min. Find the||| the train B is 50% more in length than the platform P1 passed by train A. The train A runs at a speed of 80 km/hr, while the other is 25% slower and 50% longer.
