x=14
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
6! If you do 60 times 6 you get 360.
