Question 1017201
An airplane flies out of New Orleans to Atlanta at a rate of 320 mph. It returns at a rate of 280mph. The total travel time is 3 hours. How long did it take to get to Atlanta.
--------------
Avg speed = 2*320*280/(320+280) = 896/3 mi/hr
Total time = 3 hrs
RT distance = 896 miles --> 448 mi each way
-------
Time to ATL = 448/320
= 1.4 hours
