MohanRaj  (11 years ago)

avg speed of train from manipur=X/4 KMPH
avg speed of train fromDispur=2X/7 KMPH

[X/4*Y]+2X/7*[Y-2]=x

Y/4+2[y-2]/7=1

7y+8[y-2]=28

15y=44

y=2 hrs 56 min It means 8:56 am

Suppose distance between Dispur and manipur is 28 kms.
Then speed of first train = 28/4= 7 kmph
speed of 2nd train = 28/3.5= 8 kmph

if trains met after t hrs from 6 AM, then
7t+8*(t-2) = 28
15t= 44
t= 44/16 hrs = 2 hrs 56 mins.

so trains cross each other at 08:54 hrs.

t1 : t2 :: 4:3.5
so total distance 14km
now in 8-6 a cover 7 km , remaining 7 km they will meet so
time to meet = 7/4+3.5 --> 7/7.5 = 56 min
now time to meet= 8.56 ans
