A vessel in latitude 55° 12' N sails on course 270° T and make a Dlo of 21° 36.6'. If the time taken was 3 days 2 hours, find the vessel's speed.
Given:
Time = 3 days 2 hrs or 74 hrs
Latitude = 55° 12' N
Difference Of Longitude = 21° 36.6'

Vessel's Speed
Solution:
1. We have to solve first for the distance traveled.
Distance = Dlo × Cos Latitude
= 21° 36.6' × Cos 55° 12'
= 12.33 miles
2. Now solving for the vessel's speed.
Speed = (Distance ÷ Time) × 60
= (12.33 ÷ 74) × 60
= 0.16662 × 60
= 10 knots
