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

d1/d2 + d2/v2 = 0.500km/v1 + 3.50km/2v1 = 0.250h

2. Relevant equations

v2 = 2v1

3. The attempt at a solution

The answer is 9.00km/h but I keep coming up with 5.33. I know this is simple algebra but I am missing something in the order of operations.

0.500km/v1 + 3.50km/2v1 = 0.250h

4.00km/3v1 = 0.250h

4.00/(0.250h)(3) = v1

v1 = 5.33 ??
