Answer:

Step-by-step explanation:

b and c are the speeds of the boat and current, respectively.

Traveling upstream, the boat moves b-c km per hour.

Traveling downstream, the boat moves b+c km per hour.

b-c = (60 km)/(½ h) = (120 km)/h

b+c = (60 km)/(⅓ h) = (180 km)/h

Adding the equations together,

2b = (300 km)/h

b = (150 km)/h

c = (30 km)/h
