Can you please tell me the formula of density? I know it has D, M,V but how is it written?

A jet skier leaves a dock at 8 a.m. and travels due west at 36 km/h. A second jet skier leaves the same dock 10 min later and travels due south at 44 km/h. At what time of day, to the nearest minute, will the two jet skis be 20 km apart? 

Bill and Ben are on a bridge, timing how long it takes stones they have dropped to hit the water below.  A quadratic relation can be used to determine the distance, D, in metres, that ta stone will fall in the time, t, in seconds after it is realeased.  In this relation, a = -0.5g, where g is acceleration due to gravity, which is approximately 9.8 m/s² on Earth.  Ben starts a timer when Bill releases a stone, and he stops the timer when the stone hits the water below.  The mean time of serveral trials is 3 s.

a) Determine a quadratic function that models the falling stones.

b) How high above the water are Bill and Ben? Explain your answer.

c) On Saturn's moon, Titan, the value of g is 1.35 m/s^2.  Suppose that Bill and Ben are astronauts and they are standing at the top of a cliff on Titan.  If they record the time for a stone to fall from their hands to the bottom of the cliff as 3 s, how high is the cliff, to the nearest hundreth of a metre?
