Question: The ratio of the speeds of two cars is 3:4. If the faster car travels 120 km in 2 hours, how far does the slower car travel in the same time?

Options:

1. 80
2. 90
3. 100
4. 70

Correct Answer: 80

Solution:

Let the speeds be 3x and 4x. Given 4x = 60 km/h, x = 15. Therefore, slower car\'s speed = 3x = 3*15 = 45 km/h. Distance = speed * time = 45 * 2 = 90 km.
