Finding time taken for the following situation.

A ship can travel at a speed of 36 km/h in still water. There is a sea current flowing from east to west at a constant speed of 15 km/h.

Given that the ship is about to travel vertically north, with a distance of 20 km, what is the time taken for the ship to reach its destination?

please include detailed explanations...

you guys, please don't go around saying ...i can do the math, so here's the rough sketch how you do it. PLEASE INCLUDE DETAILS!!!DETAILS! DETAILS!

THANK YOU!!! :)

I want to see a ship travel vertically!

1) Resultant vector is 20 km due north
2) Ship travel vector is some fraction of 36 km/h in a ENE direction.
3) Current travel vector is some fraction of 15 km/h due West.

Now what?

What you are asking for is NOT how MHF works.
