All of my teachers have told me that everyone remembers things best in groups of seven. so I would suggest to pick a continent and start in a corner and spend a couple of days studying seven countries in that area. also quiz your self every once in a while for extra help.
I hope this helps you

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
