The child is 0.530km from shore and 0.825km upstream of a boat landing what time a rescue boat sets out. If boat proceeds at its greatest speed of 18.9km/hr relative to the water, what angle (in degrees) does the boat velocity make with shore?

How long does it take the boat to reach the child?

Question2
