Distance - Speed and Time

I am trying to set up a simple table for distance speed and time using two variables. These are:- ship's speed and departure time from Southampton.

I want to show the arrival time at the Azores using the 24 hour clock system. in fact all hours should reflect the 24 hours clock system.

I have now become somewhat lost.

A sample of he file is attached.

Any help would be appreciated.

The table is for a fact fiction book.
