In one trip the logboat brings about 20 kg of fish. But other types of boats bring a bigger catch as given in the table. The table also shows the speed of each type of boat, which is how far each boat goes in one hour. Look at the table and calculate -
- If a long tail boat has to travel 60 km how long will it take?
Type of boat | Catch of fish in one trip (in kg) |
Speed of the boat (how far it goes in one hour) |
Log boat | 20 | 4 km per hour |
Long tail boat | 600 | 12 km per hour |
Motorboat | 800 | 20 km per hour |
Machine boat | 6000 | 22 km per hour |

Speed of long tail boat = 12 km per hour
Time = `"Distance"/"Speed" = 60/12` = 5 hour
Hence, the long tail boat will take 5 hours to travel 60 km.
