We were told that Aubrey paints 4 square feet of her house each minute.

Recall that 1 minute = 60 seconds.

The statement can be written as

Aubrey paints 4 square feet of her house each 60 seconds

If x represents the number of square feets that she paints in 20 seconds, it means that

4 = 60

x = 20

By cross multiplying, it becomes

60 * x = 4 * 20

60x = 80

x = 80/60

x = 1.333

Rounding to the nearest tenth, it becomes 1.3 square feet

She paints 1.3 square feet in 20 seconds
