Answer 1

Answer:

Step-by-step explanation:

$\mathcal\green{\fcolorbox{blue}{azure}{ANSWER}}$

Assuming all painters paint at the same rate let P = speed of a single painter

speed = distance/time

4 P = 1 House / 10 Days

P = 1 House / 40 Days

Let T = Time it takes for five painters.

5 P = 1 House / T

5(1/40) = 1 /T

1/8 = 1 /T

T = 8 Days

Answer 2

Answer:

Assuming all painters paint at the same rate let P = speed of a single painter

speed = distance/time

4 P = 1 House / 10 Days

P = 1 House / 40 Days

Let T = Time it takes for five painters.

5 P = 1 House / T

5(1/40) = 1 /T

1/8 = 1 /T

T = 8 Days
