A boat travel due east for distance of 15miles it then travel due north for 20miles?

Question

at which point does it drop anchor. how many miles from its starting point

Answer 1

It drops it anchor at the coordinates [15,20]. Now you didn't give the coordinates for the starting point, but assuming that the starting point is on the origin, specifically coordinates of 0,0, then it is palpable that the distance traveled is 25 miles.
