Answer:
Step-by-step explanation:
Given:
Each city is exactly 120 miles from the other two.
Average rate from city A to city B = 60 mi/hr
Average rate from city B to city C = 40 mi/hr
Average rate from city c to city A = 24 mi/hr
We need to find the Dale's average rate for the entire trip.
Solution:
First we find the total time and total distance by following way.
Time taken to travel from A to B =
Time taken to travel from B to C =
Time taken to travel from C to A =
So, total time taken =
Total distance = 120 + 120 + 120 = 360 miles
Using average speed formula.
Therefore, the average rate for the entire trip
