Boat sailing speed time distance graph If you know two of the variables time, speed and distance then this graph can be used to approximately calculate the third variable.

Find your boat speed over a known distance in a given time

example: if you have travelled 4.5 miles in 55 mins then your speed is 5 knots

Find the time it will take to travel a certain distance at a given speed

example: if your speed is 5 knots then it will take 55 mins to travel 4.5 miles

Find the distance you have travelled in a given time if you know your boat speed

example: if you have being going at 5 knots for 55 mins then you have travelled 4.5 miles
