2 hours 37 min and 30sec because 280*3=840 and 840/320=2.625

0.625*60=37.5 thats the time in min the .5 is 30 sec

so its 2 hours 37 min and 30 sec hope this helps

The distance either way is the same, let the distance be x miles

so , since Time = Distance/Rate

x/320 + x/280 = 3

solve to get x = 448 miles

so time for first flight = 448/320 hrs

= **1.4 hrs or 1 hour and 24 minutes**

check

first flight = 448/320 = 1.4

second flight= 448/280 = 1.6

total time = 3 hrs.
