SOLUTION: The distance traveled by a car with constant speed is directly proportional to the length of time traveled. If the car travels 150km in 2 hr, then how far will it travel in 7 hrs?

Question 162901: The distance traveled by a car with constant speed is directly proportional to the length of time traveled. If the car travels 150km in 2 hr, then how far will it travel in 7 hrs?

Well, if it travels 150km in 2 hours, then in 1 hour it will have travelled half as far - ie 75km.
or,mathematically put : speed = distance / time = 150/2 = 75 km/h
So if it does 75km in 1 hour then in 7 hours it will go 7 times as far as that.
distance = 7 X 75 = 525 km.
