Question

37 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?
a 1.5
b 10
c 2
d 3

Explanation:

Step1: Define variable for time

Let $t$ = time (in hours) until they meet.

Step2: Calculate total distance covered

Aaron's distance: $3t$, Zhang's distance: $2t$. Sum equals 10 mi:
$$3t + 2t = 10$$

Step3: Simplify and solve for t

Combine like terms:
$$5t = 10$$
Divide both sides by 5:
$$t = \frac{10}{5} = 2$$
