Question: If two cars start from the same point and travel in the same direction at speeds of 60 km/h and 80 km/h, how far apart will they be after 3 hours?
Options:
Correct Answer: 60 km
Solution:
Relative speed = 80 km/h - 60 km/h = 20 km/h. Distance apart = Relative speed × Time = 20 km/h × 3 h = 60 km.
