Julissa is running a 10-kilometer race at a constant pace. After running for 18 minutes, she completes 2 kilometers. After runni

polet [3.4K]

For this case we have the following variables:
t: number of minutes
k: number of kilometers
We have an equation of the form:
$k = r * t
$
Where,
r: proportionality constant
To find r, we must replace a value of k and a value of t.
We have then:
$2 = r * 18
$
Clearing r we have:
$r = 2/18

 r = 1/9$
Substituting we have:
$k = (1/9) * t
$
We checked for t = 54:
$k = (1/9) * 54

k = 6$
Therefore, the equation is correct.
Answer:
An equation that can be used to represent k, the number of kilometers Julissa runs in t minutes is:
$k = (1/9) * t$

3/5 of gallon of juice is poured equally into 6 glasses . How much juice is in each glass?

Setler [38]

Hi there! For this question, we will have to divide. When it comes to dividing fractions, we keep, change, flip. In other words, keep the first fraction the same, change division into multiplication, and flip the second fraction over by its reciprocal. In this case, 3/5 stays the same and 6/1 becomes 1/6. 3/5 * 1/6 is 3/10 or 1/10 in simplest form. There. There are 1/10 gallon of juice in each glass.
