Question

a train covers a distance between two stations A and B in 45 minutes .if the speed of train is reduced by 5 km /hr, then it covers
the distance between the stations A and B is ?​

Answer 1

Answer:

➡️Let the speed of the train be" x km/h "

distance between AB = 45/60 × x

speed decreased by 5 km/h

speed = (x-5)

d= (x-5) × 48/60 km

But d is same

so

45/60 × x = 48/60 × (x-5)

45x=48x-240

3x=240

x = 240/3

x= 80

➡️speed of train is 80 km/h

time = 45 minutes = 3/4 hour

d=rt

80 × 3/4

=60 km

➡️Distance between A & B = 60 km
