.
This problem needs you to apply the "distance formula":
d = rt
where
d is distance
r is rate or speed
t is time
.
"distance airplane traveled" = "distnce jet traveled"
.
Let x = hours "airplane" was flying
x-1 = hours "jet" was flying
.
180x = 333(x-1)
180x = 333x - 333
180x + 333 = 333x
333 = 153x
333/153 = x
2.176 hours = x
