The boat moves along the river at a speed of v1 = 5km. h-1 and upstream v2 = 2km. h-1. What is the current P's and boat L's speed relative to the water?

Correct answer:

P =  1.5 km/h
L =  3.5 km/h

Step-by-step explanation:

v1=5 km/h v2=2 km/h  L+P=v1 LP=v2 L+P=5 LP=2  L+P=5 LP=2  Row2Row1Row2 L+P=5 2P=3  P=23=1.5 L=5P=51.5=3.5  L=27=3.5 P=23=1.5=1.5 km/h
