How long was the flight from New Orleans to Atlanta?
:
Find the distance first, then it is an easy calculation to find the flight times
:
Let d = the one-way distance
:
Write a time equation; time = dist/speed
:
To time + return time = 3 hrs + = 3
Multiply by the LCM of the denominators, 2240
2240* + 2240 = 2240(3)
Cancel the denominators, you have
7d + 8d = 6720
15d = 6720
d = 6720/15
d = 448 mi
:
Find the time N.O. to Atl = 1.4 hrs
