A total distance of 750 km was traveled partly by car (x km) and partly by train (y km). If the train journey exceeded the car journey by 150 km, what is the ratio of the distance traveled by car to that by train (x:y)?
Explanation
Given that x + y = 750 and y = x + 150, substituting gives x + (x + 150) = 750, which simplifies to 2x = 600, so x = 300. Then y = 450. Therefore, the ratio x:y = 300:450 = 2:3.
