Question

X and y are two stations 600 km apart. a train starts from x and moves towards y at the rate of 25 km/h. another train starts from y at the rate of 35 km/h. how far from x they will cross each other?

Answer 1

Answer:

Step-by-step explanation:

T=[600/(35+25) ]=10h

D= 25*10=250

Answer 2

Answer:

250km far from X station, trains will cross each others.

Step-by-step explanation:

• In context to the given question, we have to find the distance from x station when the train will cross.
• given,

1. Distance between two stations (d)= 600 km
2. Speed of Train A (Sa) = 25 km/h
3. Speed of Train B (Sb) = 35 km/h

Solution:

we know that;

Time of crossing of two train in  opposite direction =  $\frac{d}{Sa + Sb}$

Time of crossing of two train in  opposite direction =  $\frac{600}{25+35}$

Time of crossing of two train in  opposite direction = 10 hours

It means after 10 hours; trains will cross each other

Distance from X station = speed x time

Distance from X station = 25 x 10

Distance from X station = 250 km

∴ 250km far from X station, trains will cross each others.

ADDITIONAL INFORMATION :

If the train are moving in the same direction: $\frac{d}{Sa - Sb}$
