Question

out of 75 km ,a train covered a distance of 35 km 475 m.What is the remaining distance that the train has to cover.

Answer 1

til 11 am, train A covers distance of 65 km. So remaining distance is 390-65=325 km.

relative speed = 100kmhr
So to cover 100km ---- 1hr

therefore to cover 325km --- xx hr
x=325100=3.25x=325100=3.25 hrs

Hence the trains meet at 11am + 3.25hrs = 2.25 pm
