please help me to solve the question

thanks

Consider the hyperbolic paraboloid z = z - 32. A drone is programmed to fly along the surface of the hyperbolic paraboloid. The flight instruments measure the velocity in the z, y and & directions as di = 2 dy dt dt = 5 dz = 4. dt The GPS measures z = 10, but the GPS does not measure y (to keep costs down). What is the y co-ordinate? The chain rule can tell us! It's y =
