Question 162570: im having trouble with two questios, i just dont understand them. i know i have to use the formula for distance or radius (r = xsqaured + y sqaured) but i dont know how to apply it. the questions are
A rock dropped into a pond sends out a circular ripple whose radius increases steadily at 6cm/s. A toy boat is floating on the pond 2 m east and 1 m north of the spot where the rock is dropped. How long does it take for the rippe to reach the boat
the second question is
A triangle has vertices at s (6,6), t(-6,12), and u(0,-12). SM is the median from the vertex S. Find the coordinates of the point that is two-thirds of the way frm S to M.
I dont know how to apply toe distance formuls, radius or mid point formula. I really need your help, i have a test tomorrow.
Thank you

Question 168322: can anyone help with the following assignment question,
Two aircrafts take off simultaneously from different airports. As they climb, their positions relative to an air traffic control centre t minutes later are given by the vectors:
r1 = 4i-30j +t(8i+2j+0.3k)
r2 = 12i+26j+ t(6i-3j+0.8k)
where i direction is due east, the j is due north and k is vertical distance and the units are kilometres.
a) find the coordinates of the point over the groun where the two planes cross
b) find also the difference in height and time that they both pass this point.
this is a completely different question to the examples we have done in the handouts and lessons so i am really struggling with this.
