A)

d =240/a

B) 2 loads of gravel

Step-by-step explanation:

Step 1:

Given one load of gravel is 240 ft2.

We have depth = 240/area

Hence the inverse variation model is d =240/a

Step 2 :

The length and breadth of the playground is 40 ft and 24 ft

The depth of the playground is 6 in = 6/12 ft

Hence the volume of the given playground is 40 * 24 * 6/12 = 480 cu ft.

There is  240 ft2 of gravel in one load

So we need 480 cu ft of gravel =  480/240 = 2 loads of gravel.
