A rocket traveled 12,000 miles in the first four hours. Then the rocket traveled 8000 miles in the next four hours. What was the rocket’s average speed, in miles per hour, for these 8 hours?

Hello Guest!

 

\(average\ speed=\frac{(12000+8000)miles}{(4+4)hours}=\color{blue}2500\ miles\ per\ hour\)
