Question

Kathleen jarred 12 liters of jam after 4 days. How much jam did Kathleen jar if she spent 6 days making jam? Assume the relationship is directly proportional.

Answer 1

Given parameters:

Number of liters of jam = 12 liters

Number of days = 4 days

Unknown:

Number of jams jarred in 6 days = ?

Solution:

Let us first find the rate of Kathleen in this jarring work;

     Rate  = $\frac{Number of jams}{Number of days}$

     Rate  = $\frac{12}{4}$   = 3liters/day

Now, the number of jams in 6days;

    Number of jams = Rate x number of days

    Number of jams = 3 x 6  = 18jams

The number of jams jarred in 6 days is 18
