HELP Question HelpDetermine whether you can use proportional reasoning, and then solve.It takes 3 hours for Marty and Cora to weed a garden. How long will it take 6 people to weed the samegarden if they all work at the same constant rate? Explain.

Answer 1

we know that

It takes 3 hours for Marty and Cora to weed a garden

so

Two people weed a garden (100%) in 3 hours

so

If you have 6 people, the time is divided by 3

so

6 people weed a garden in 1 hour

the relation is not proportional

the relation is a inverse variation

Let

y -----> the number of people

x -----> the time in hours

the equation is equal to

yx=6
