Two trains each 100 m long, moving in opposite directions, cross each other in 8 seconds. If one is moving twice as fast the other, then the speed of the faster train is `30\ k m//h r` b. `45\ k m//h r` c. `6\ k m//h r` d. `75\ k m//h r`

Two trains, one 150 m long and the other 130 m long, coming from opposite directions crossed each other in 7.2 seconds. The sum of speed of the two trains every hour would then be:

Two trains, one 153 m long and the other 127 m long, coming from opposite directions crossed each other in 7.2 seconds. The combined speed of the two trains every hour would then be:

A journey of 192 km between two cities takes 2 hours less by a fast train than by a slow train. If the average speed of the slow train is 16 km/hr less than that of the fast train, then the average speed of the fast train is 32 k m//h r b. 48 k m//h r c. 36 k m//h r d. 64 k m//h r

A train passes a platform 90 m long in 30 seconds and a man standing on the platform in 15 second. The speed of the train is a. 12. 4 k m//h r b. 14. 6 k m//h r c. 18. 4 k m//h r d. 121. 6 k m//h r

A train 108 m long moving at a speed of 50 km/hr crosses a train 112 m long coming from opposite direction in 6 seconds. The speed of the second train in 48 k m//h r b. 54 k m//h r c. 66 k m//h r d. 82 k m//h r
