Question

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 -

• About how much fish in all will each type of boat bring in seven trips?

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

Answer 1

Type of boat	Catch of fish in one trip (in kg)	Catch of fish in 7 trips (in kg)
Log boat	20	7 × 20 = 140 kg
Long tail boat	600	7 × 600 = 4200 kg
Motor boat	800	7 × 800 = 560 kg
Machine boat	6000	7 × 6000 = 42000 kg
