WebWe can subtract 64 from both sides, we get 12. 12 times the derivative of h with respect to time is equal to negative 64. And then we just have to divide both sides by 12. And so now we get a little bit of a drum roll. The derivative, the rate of change of h with respect to time is equal to negative 64 divided by 12. WebJan 9, 2016 · Let the first boat be at the origin at noon, and let its position vector at time t be a _. Then. a _ = ( 0 15) t. Likewise let the second boat have position vector at time t given by. b _ = ( 0 30) + ( 20 0) t. The displacement of B relative to A is. b _ − a _ = ( 0 30) + ( 20 − 15) t. The distance between them at time t is.
