Question 521359: An air plain flies from new Orleans to Atlanta at an average rate of 320 mph. The air plane then returns at an average rate of 280 mph. The total travel time is 3 hours. What was the flying time from new Orleans to Atlanta? From Atlanta to new Orleans? Answer by Math_prodigy(24) (Show Source):
You can put this solution on YOUR website! d=vt d-distance, v-aver speed, t-time
Let n be the time from O to A then d=320n
Let m be the time from A to O then d=280m
n+m=3
n=3-m
"d" is the same from O to A and from A to O
320n=280m
320(3-m)=280m
960-320m=280m
960=600m
m=1.6
n=3-1.6 n=1.4
