Solution
| Type of boat | Catch of fish in one trip (in kg) |
Speed of the boat (how far it goes in one hour) |
| Log boat | 4 km per hour | 4 × 6 = 24 km |
| Long tail boat | 12 km per hour | 12 × 6 = 72 km |
| Motor boat | 2 km per hour | 20 × 6 = 120 km |
| Machine boat | km per hour | 22 × 6 = 132 km |
