# A ship is 20km west of another ship B. If a sails at 10km/hr. and at the same time B sails north 30km/hr. Find the rate of change of distance between them at the end of half hour.

The rate of change in the distance between two ships can be calculated by using the Pythagorean theorem and basic physics. The equation for this is as follows: d = √(x^2+y^2) where x is the horizontal distance between them, y is the vertical distance, and d is the total distance. In this scenario we have a ship A that is 20 km west of another ship B. If A sails at 10km/hr while B sails north at 30km/hr then we can calculate the rate of change in their distance after half an hour.

First, let us calculate how far each ship will have moved in 30 minutes. Ship A will have gone 300 km (10km/hr * 30min), and Ship B will have gone 450 km (30km/hr * 15min). This means that after half an hour, Ship A has moved 300 km west from its original position and Ship B has moved 450 km north from its original position.
