Question 57256
Hello,

I will assume that they start at the same time.

Remember that: Speed * Time = Distance

Call t the time that the plane needs to get from A to B.

Call x the distance between A and B.

Then we have that: 605*t = x
But we also know that 33*(t+104) = x
(because the boat takes 104 hours more in time)

This gives us 605*t = x = 33*(t+104)

605t = 33t + 3432

t= 6

x = 605*6 = 3630
