solve

Write the Leibniz notation for the derivative of the given function and include units. The distance to the ground, D, in feet, of a skydiver is a function of the time t in minutes since the skydiver jumped out of the airplane. The number, N, of gallons of gas left in a gas tank is a function of the distance, D, in miles, the car has been driven.
