Two particles A and B get 4m closer each second while traveling in opposite direction They get 0.4 m closer every second while traveling in same direction. The speeds of A and B are respectively :

Two cars get closer by 8 m every second while traveling in the opposite directions. They get closer by 0.8 m while traveling in the same directions. What are the speeds of the two cars ?

Two cars get closer by 8 m every second while traveling in the opposite directions. They get closer by 0.8 m while traveling in the same directions. What are the speeds of the two cars ?

Two trains cross each other in 12 seconds , when they travel in opposite directions and they take 60 seconds when they travel in the same direction. The possible speeds of the trains, (inm/sec), can be:

Two trains whose respective lengths are 200 m and 250 m cross each other in 18 s, when they are travelling in opposite direction and in 1 min, when they are travelling in the same direction. What is the speed of the faster train (in km/h)?

Two trains whose respective lengths are 200 m and 250 m cross each other in 18 s when they are travelling in opposite direction and in 1 minute when they are travelling in the same direction.What is the speed of the faster train(in km/h)?

Two trains of equal lengths take a minute to cross each other when traveling in the same direction.They take 20 seconds to cross each other when traveling in opposite directions. Find the ratio of the speeds of the faster and the slower train.

The distance between two particles is decreasing at the rate of 6 m/sec,when they travel in opposite direction to each other. If these particles travel with same speeds and in the same direction, then the separation increase at the rate of 4 m/sec. The particles have speed as

There are two trains running on two parallel tracks. Length of each train is 120 m. When they are running in opposite directions, they cross each other in 4 seconds and when they are running in the same direction they cross in 12 seconds. What is the speed of the faster train?
