A girl is walking 10 miles every 3 hrs whats her average speed ♥
Nookie1986 [14]
We want to find miles per hour.
Speed is distance over time.
So take 10 miles (distance) / 3 hours (time)
This is the same as 10/3.
10/3 = 3 and 1/3
Therefore, the girl is going 3 and 1/3 miles per hour.

x + 2 - 2 = -12 - 2

x = -14

So therefore, that is how you found your answer: x = -14
