:
Let t = travel time of the southbound ship
then
(t-2) = travel time of the northbound ship
:
We know the total traveling distance of both ships = 2230 mi
:
Write a distance equation: Dist = speed * time
:
South dist + north dist = 2230 mi
28t + 35(t-2) = 2230
28t + 35t - 70 = 2230
63t = 2230 + 70
t = 2300%2F63
t = 36.5 hrs after the southbound ship leaves the canal
:
:
Check:
28(36.5) + 35(34.5) =
1022. + 1207.5 = 2229.5 ~ 2230

I think the time for northbound ship should be (t+2)rather than (t-2).Am I wrong please justify.
