Question

Aaron starts walking at a rate of

3 mi/h on a road toward a store
10 mi away. Zhang leaves the store when Aaron starts walking, and
he walks toward Aaron along the same road at 2 mi/h. How many hours will pass before they meet?

Answer 1

they will have to walk for 2 hours before they meet. zhang will be 4 miles away form the store and aaron will be 6 miles away from where he started show they are going to be both 4 miles away from the store in 2 hours

Answer 2

2 hours will pass before they meet

Explanation:

Total distance = 10mi

Aaron = 3mi/h

Zhang = 2mi/h

Let y be the number of hours for them to meet.

The expression is given as

3y + 2y = 10

solving for y, we have

5y = 10

y = 10/5

y = 2 hrs

Therefore, 2 hours will pass before they meet.
