If the two ships are travelling at speeds of 15 knots and 18 knots, heading north and east, respectively, how far away are the two ships from each other two hours after leaving the port? Use 1 knot= 1.852 km/hour.
:
The distance between the two ships is the hypotenuse of a right triangle
a^2 + b^2 = c^2, where:
a = 2 * 15 * 1.852 = 55.56 km
b = 2 * 18 * 1.852 = 66.67 km
c = the distance between the ship after two hours
c+=+sqrt%2855.56%5E2+%2B+66.67%5E2%29
use your calc
c = 86.79 km apart after two hrs
