Provide an appropriate response.A plane averaged 300 mph on a 600 mile trip and then returned over the same 600 miles at the rate of 
What was the plane's average speed for the entire trip? Give reasons for your answer.
What will be an ideal response?
Since the plane averaged 300 mph on the first 600 miles, the first part of the trip took 
The return trip took 
The entire trip of 1200 miles took 
So the average speed was
