Some boats have motors and go further into the sea. since they go far out they can catch more fish. These boats travel faster, at a speed of about 20 km in one hour.
How far would the motorboats go in three and a half hours?

Solution
In 1 hour the boat goes 20 km.
Hence, in 3 hours the boat will go
= 3 × 20 = 60 km
And in `1/2` hour the boat will go
= `20/2` = 10 km
So, in 3 and a half-hour, the boat will go
= 60 + 10
= 70 km
