Solution:

(2) Let the speed of the bus be x kmph and distance be y.
∴ Original time required to reach destination =

y/x

h
Time required at the speed of 20 kmph =

y/20

h
Time required at the speed of 25 kmph =

y/25

h
∴ According to the question,

{y}/{20}-1= {y}/{25}+1

⇒

5y – 4y = 200

⇒

y = 200
