71 From stations A and B, two trains start moving towards each other with the speeds of 150 km/h and 130 km/h, respectively. When the two trains meet each other, it is found that one train covers 20 km more than that of another train. Find the distance between stations A and B:
72 A train overtakes two persons who are walking at the rate of 4 km/h and 8 km/h in the same direction and passes them completely in 18 and 20 s, respectively. Find the length of the train:
73 Two trains 100 metres and 120 metres long are running in the same direction with speeds of 72 km/hr and 54 km/hr. In how much time will the faster train cross the second?
74 A train 75 metres long overtook a person who was walking at the rate of 6 km/h and passed 3 him in 72 seconds. Subsequently, it overtook a second person, and passed him in 6 4 seconds. At what rate was the second person travelling?
75 The distance between two stations A and B is 138 km. A train starts from A towards B and another from B to A at the same time and they meet after 6 h. The train travelling from A to B is slower by 7 km/h compared to other train from B to A, then find the speed of the slower train?
76 How many seconds will a 500 metre long train take to cross a man walking with a speed of 3 km/hr in the direction of the moving train if the speed of the train is 63 km/hr?
77 Two trains are moving in opposite directions at 60 km/hr and 90 km/hr respectively. Their lengths are 1.1 km and 0.9 km respectively. The time taken by the slower train to cross the faster train in seconds is:
78 A train covers distance between two stations A and B in 2 h. If the speed of train is reduced by 6 km/h, then it travels the same distance in 3 h. Calculate the distance between two stations and speed of the train
