Marks: +1, -0

Two trains started coming towards each other on parallel tracks from Stations A and B respectively, one from A to B and the other from B to A. They cross each other after 1 hour and the faster train reaches

B 5/6

before the other train reaches A. Find the speed of the slower train if the distance between both the stations is 500 km.

200 km/hour
250 km/hour
300 km/hour
100 km/hour
400 km/hour

Solution:

Let the speed of the faster train =

S_1

And speed of slower train =

S_2

{500}/{S_1+S_2}

= 1

S_1+S_2

= 500

{500}/{S_1}-{500}/{S_2}

5/6

Now by using given options,
Speed of the slower train = 200 km/hour

{500}/{200}-{500}/{300}

5/6

Hence, the speed of the slower train
= 200 km/hour.
