Blade width at the bulldozer is 3m. How much area a bulldozer can level in 1 hour at a speed of 18 km / h.

a = 3 m.

t = 1 h = 3600 s.

V = 18 km / h = 5 m / s.

S -?

We will assume that the bulldozer moves in a straight line when leveling the site.

We express the area of the site S by the formula: S = a * L, where a is the width of the dozer blade, L is the distance traveled by the tractor.

Let us express the path of the tractor L by the formula: L = V * t, where V is the speed of the tractor, t is the time of the tractor.

The area of the site S will be determined by the formula: S = a * V * t.

S = 3 m * 5 m / s * 3600 s = 54000 m2.

Answer: in an hour of work, a tractor can level a site with an area of S = 54,000 m2.
