Answer 2

A tractor can plough 13.5 hectares in 4.5 hours

Step-by-step explanation:

If a tractor can plough 12 hectares in 4 hour

⇒A tractor can plough 1 hectare in $\frac{4}{12}$

If the tractor is ploughing at the same speed.

Then,

A tractor can plough 13.5 hectares in $\bold {\frac{4}{12}\times 13.5\ hours}$

                                                            = $\frac{1}{3}\times 13.5\ hours$

                                                            = 4.5 hours
