Agirl is walking 10 miles every 3 hrs whats her average speed ♥

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.

C. expression because any expression or equation may contain more than one variable

The year before the 10s so it was like when caveman were alive
