Danny sails a boat downstream. The wind pushes the boat along at 21 km/hr. The current runs downstream at 15 km/hr. What is the actual velocity of the boat?

Respuesta :

Answer:

36 km/h

Explanation:

The total velocity is the sum of the two velocities that add to the movement of the boat.

Since the wind pushes the boat at 21 km/h and the current that runs in the direction of the movent of the boat is 15 km/h, the total velocity at wich the boat moves is:

21km/h + 15 km/h = 36 km/h
