Answer:

the answer to this question is 3:30...as we know

the which will be travel is 90km

as train start at 2:15 ...at 3:15 it reach at 72 kilometres..

then the left distance is 18km ....

if 72km in one hour ...then 1km takes 10/12 time .....

so 18km take 18*10/12 =15minute ...

so just add 15minutes in 3:15 which is 3:30

3:30pm is correct

If you know the answer add it here!
