(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A boy walks at an average speed of 3 miles per hour to his school, and then runs back at an average speed of 5 miles per hour along the same route. The total travel time is 1 hour. What was the total distance traveled?

3. The attempt at a solution

OK it's a practice question I saw in my SAT prep book, and I feel soooo incredibly stupid to not be a ble to solve this. The answer is 3.75 miles, btw.

d1 = d2

dt = d1 + d2

t1 + t2 = 1 hr

d1 = v_{1}t_{1}

d2 = v_{2}(1-t_{1})

d_{t}= v_{1}t_{1}+ v_{2}-v_{2}t_{1}

d_{t }= 3t_{1}+ 5 - 5t_{1}

Then I get stuck here.

Pretty sure I am over complicating the problem, so could somene help me?
