Answer:

p = 281.25

Step-by-step explanation:

p = kd

125 = k(2)

125/2 = 2k/2

125/2 = k

p = (125/2)(4.5)

p = 281.25

Answer:

Pressure is 281.25 Pascal

Step-by-step explanation:

The pressure of P at the bottom a swimming pool varies directly as the dept D of the water.

P = kD ; where P is the pressure, D is the dept and k is the constant.

if P = 125 Pascal in D = 2 meters

P = kD

125 Pascal = k * ( 2 meters)

k = 125 Pascal / 2 meters

k = 62 1/2 or 62.5

if D = 4.5 meters, find P

P = kD

P = ( 62.5 ) * ( 4.5 meters )

P = 281.25 Pascal
