The weight P in pounds that a beam can safely carry is inversely proportional to the distance D in feet between the support beam

Leona [35]

Rewriting the function we have:
p = 9200 / D
We must in this case clear the value of D.
We have then:
D = 9200 / p
Substituting the value of p = 1600 lb we have:
D = 9200/1600
D = 5.75 feet
Answer:
the distance between supports that is needed to carry 1600 lb is:
D = 5.75 feet
