How far apart are the trains 1 hour before they meet?

The combined rate of the two trains is 30 + 40 = 70 miles per hour. Therefore 1 hour before they meet the must be 70 miles apart (in the final 1 hour they will cover 70 miles to meet).

When two trains collide this is an example of?

When it reaches train B it makes an instantaneous reversal of direction and flies back toward train A. It continues to change direction every time it runs into a train until both trains and the bee meet in a spectacular crash. What total distance did the bee fly before the big collision?

When two trains cross each other in the same direction?

When two bodies move in the same direction then the Relative Speed = Difference of Speeds i.e for a person a sitting in a train moving with a speed of 60 km/hr in the west direction, another train which is going towards the west with a speed of 40 km/hr, will appear to move at a Speed of (60-40) = 20 km/hr.

At what time trains cross each other?

If two trains of equal lengths and different speeds take t1 and t2 time to cross a pole, then the time taken by them to cross each other if the train is moving in opposite direction = (2×t1×t2) / (t2+t1)

Can two trains collide?

A major incident has been declared after two trains collided in Salisbury, leaving several people injured. The crash happened at 18:46 GMT when one train hit an object in a tunnel, and the second train then collided with it due to signalling problems. …

At what time the trains cross each other?

Hence, the trains will meet at 7:56am .

How far apart do trains leave stations at the same time?

Two trains leave stations 456 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour while the other travels at 85 miles per hour.

How long would it take for the two trains to meet?

It would take 2 hours and 24 minutes for the trains to meet. Answer by lwsshak3(11628) (Show Source): You can put this solution on YOUR website! Two trains leave stations 456 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour while the other travels at 85 miles per hour.

How do you calculate the distance between two trains?

Two trains starts simultaneously from the stations A and B towards each other at the rates of u and v km/h respectively. When they meet it is found that the second train had traveled x km more than the first. Then the distance between the two stations (i.e., between A and B) is x (u+v)/ (v-u) km 1.A boy runs 200 metres in 24 seconds.

How do you calculate time taken by a train to cross?

Time taken by the train to cross a man = x/ (u-v) where, both are moving in the same direction and x= length of the train; u= speed of the train and v= speed of the man. Time taken by the train to across a man running in the opposite direction= x/ (u+v)
