QUESTION-:. 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 ?
A) 80 kms
B) 60 kms
C) 45 kms
D) 32 kms

$\boxed{Answer-:}$60kms

$\huge\boxed{SOLUTION-:}$

➡️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
