- A man driving his bike at 24 kmph reaches his office 5 minutes late. Had he driven 25% faster on an average he would have reached 4 minutes earlier than the scheduled time. How far is his office?

Correct Answer - (3)
Solution:
Let x km be the distance between his house and office.
While traveling at 24kmph, he would take  hours. While traveling at 30 kmph, he would take  hours. Therefore,  (given in the problem. 5 min late + 4 min early = 9 min)
=> x = 18 km
