- 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?
(1) 24 km (2) 72 km (3) 18 km (4) Data Insufficient
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
