Two trains, one from Howrah to Patna and the other from Patna to Howrah, start simultaneously. After they meet, the trains reach their destinations after 9 hours and 16 hours respectively. The ratio of their speeds is `2:3` b. `4:3` c. `6:7` d. `9: 16`

Two trains started at the same time , one from A to B and the other from B to A . If they arrived at B and A respectively 4 hours and 9 hours after they passed each other , the ratio of the speeds of the two trains was

A starts from a place P to go to a place Q. At the same time B starts from Q to P. If after meeting each other A and B took 4 and 9 hours more respectively to reach their destinations, the ratio of their speeds is

Two trains start at the same time, one from Kolkata to Madhupur and the other from Madhupur to Kolkata. If they arrive at Madhupur and Kolkata respectively 1 hour and 4 hours after they cross each other , find the ratio of their velocities.

A and B start moving from a place X to Y and Y to X , respectively , at the same time on the same day . After crossing each other ,they complete their remaining joumeys in 5(4)/(9) hours and x hours ,respectively .If the ratio of the speeds (in km/h) of A and B is 9 :7 ,then what is the value of x ?

If a bus travels 126km in 3 hours and a train travels 315km in 5 hours, then the ratio of their speeds is: (a) 2:5 (b) 2:3 (c) 5:2 (d) 25:6

If a bus travels 126km in 3 hours and a train travels 315km in 5 hours, then the ratio of their speeds is: (a) 2:5 (b) 2:3 (c) 5:2 (d) 25:6
