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

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

One train runs from station A and B and the other from station B to A. They both start simultaneously and meet cross each other at a particular point on the route. Their speeds are in the ratio 4:3. After crossing each other the train from A to B takes 5 hours to complete the leftover 200km of journey. The speed of train from B to A after crossing reduced by 5 km//h and it covered the leftover distance in 12 hours. What is the total distance between A and B?
