A train covers a distance between station A and station B in 45 min.If the speed of the train is reduced by 5 km/hr,then the same distance is covered in 48 min.what is the distance between the stations A and B ?
Let 'd' be the distance and 's' be the speed and 't' be the time d=sxt 45 mins = 3/4 hr and 48 mins = 4/5 hr As distance is same in both cases; s(3/4) = (s-5)(4/5) 3s/4 = (4s-20)/5 15s = 16s-80 s = 80 km. => d = 80 x 3/4 = 60 kms.
