A and B start at the same time with speeds of 40 km/hr and 50 km/hr respectively. If in covering the journey A takes 15 minutes longer than B, the total distance of the journey is

The distance between two cities A and B is 330 km. A train starts from A at 8 a.m. and travels towards Bat 60 km / hr. Another train starts from Bat 9 a.m. and travels towards A at 75 km/hr. At what time do they meet?

While travelling downstream, a man can row 16 km more in 4 hours as compared to travelling upstream. What is the speed of the stream?

B walks at a speed of 9 km/h and after 9 hours of its start, C follows him on his cycle at a speed of 18 km/h. At what distance from the starting point will C catch B?

Two men start walking together to a certain destination, one at 6 km/hr and other at 7.5 km/hr. The later arrives an hour before the former. The distance is ?

180 m long Train A crosses Train B of 120 m in length which is running in opposite direction in $$ {60\over 11}$$ sec. If speed of train B is 20% more than that of train A, then find the time taken by both trains to cross each other, when they running in same direction?

There are three athletes A, B and C at a same point. A starts running from a point at a speed of 40 m/min. After 5 minutes, B starts running after A with a speed of 50 m/min. Simultaneously, C also starts running after A at 60 m/min. What distance has C covered (in m) when he catches A?

Train A of length 120 m can cross a platform of length 240 m in 18 second the ratio of speed of train A and Train B is 4 : 5. Then find the length of Train B if train B can cross a pole in 12 seconds.
