Answer:
Ok, so I don't have the answer for this one, but I think I understand the process.
Step-by-step explanation:
So to find the average rate of 2 speeds, you must add them together and then divide by two.
So for this question, I think you have to find the rate of speed for 60 miles an hour for 2.5 hours and then do the same for 75 miles for 1.5 hours. Once you have those two numbers, add them together and divide by two to get your answer.
I hope this helps!
