Question 991165
Two ships leave port at the same time. One travels north at 80 knots (that is, 80 nautical miles per hour), and the other west at 80 knots. The distance between the ships increases at a constant rate
------------------------
We know what knots means.
---
The distance between them at time t is the hypotenuse = {{{80sqrt(2)t}}} nm, t in hours
