A train M leaves City A at 5 am and reaches City B at 9am. Another train N leaves City B at 7am and reaches City A at 1030am. At what time do the 2 trains cross one another?
Correct answer: D
Explanation
Let the distance between the cities be x
They meet after y hrs after 7am
M covers x in 4hrs
N covers x in 3 1/2 i.e 7/2 hrs
speed of M =x/4
speed of N = 2x/7
Distance covered by M in y+2 hrs + Distance covered by N in
y hrs is x
x/4 (y+2) +2x/7(y)=x
y=14/15hr or 56 min
D.
