For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 325 miles in 5 hours, how many miles does it travel in 9 hours?

Answer 1

To solve this problem, we can set up a proportion using the information given.

Let x be the number of miles the car travels in 9 hours.

Since the distance traveled varies directly with time, we can write the proportion:

325 miles / 5 hours = x miles / 9 hours

To solve for x, we can cross multiply:

5 * x = 325 * 9

5x = 2925

Divide both sides of the equation by 5 to solve for x:

x = 2925 / 5

x = 585

Therefore, the car travels 585 miles in 9 hours.
