Apainting crew paints at a rate of 1 2 square foot per second. if the area of the walls in a house are 4500 square feet, how long does it take them to finish painting the house?

For this case we have the following equation:
 t = A / v
 Where,
 t: time
 A: area
 v: speed
 Substituting values we have:
 t = 4500 / (1/2)
 t = 9000 seconds
 
 It will take them to finish painting the house about:
 t = 9000 seconds
