Question: The ratio of the speeds of two cars is 3:4. If the first car travels 120 km in 2 hours, how far does the second car travel in the same time?
Options:
Correct Answer: 160
Solution:
Speed of first car = 120 km / 2 hours = 60 km/h. Let speed of second car = 4x. 3x = 60, x = 20. Therefore, speed of second car = 4*20 = 80 km/h. Distance = speed * time = 80 * 2 = 160 km.
