Question: If two cars are moving in the same direction at speeds of 60 km/h and 80 km/h, how long will it take for the faster car to overtake the slower car if they start 100 km apart?
Options:
Correct Answer: 1.5 hours
Solution:
Relative speed = 80 km/h - 60 km/h = 20 km/h. Time = Distance / Speed = 100 km / 20 km/h = 5 hours.
