First, write down the formula to solve for the rate. { ax-1, x-2 A motorboat leaves a harbour and travels at an average speed of 15 km/h toward an island. distance = time into downstream speed + time into upstream speed =(speed-3) + 30/60 (speed+3). What is being illustrated below? The total distance traveled will be d kms. you only have to change the signs because all though the speeds are the same the cars are now moving AWAY from the intersection, so dy/dt = 60, not -60, and dx/dt = 30, not -30. When solving these problems, use the relationship rate (speed or velocity) times time equals distance.
