Question: The ratio of the speeds of two cars is 2:3. If the faster car travels 180 km in 2 hours, how far does the slower car travel in the same time?

Options:

1. 120
2. 90
3. 150
4. 100

Correct Answer: 120

Solution:

Speed of faster car = 180/2 = 90 km/h. Speed of slower car = (2/3)*90 = 60 km/h. Distance = speed * time = 60*2 = 120 km.
