Answer:
47.25 mph
Step-by-step explanation:
Represent the total distance traveled as 2x. Average speed= total distance/total time
When going at 42 mph, the time would be x/42 and when going at 54 mph the time would be x/54 to travel x distance. Add x/42 and x/54 together to get 16x/378. Then divide 2x by 16x/378 to get 47.25 mph. Also this is RSM innit?
