the ship travels at 15 mph when under load and 20 mph when empty.
The ship leaves the port empty at 12:00 PM and arrives at its destination at 3:00 PM.
Empty travel time = 3 hrs
Trip distance: 3 * 20 = 60 miles
:
It takes an hour to fully load the ship and depart back to the originating port.
What time will the fully loaded ship return to the originating port?

Write a time equation for the return trip (loaded)
load time + travel time
1 + = 5 hrs from 3 pm = 8Pm
