Question

Jesse drives to work. The distance Jesse’s car travels (d) on a number of gallons of gas (g) is given by the equation d = 15g.

The constant of proportionality in terms of distance traveled per gallon of gas is

a. 15
b. 5
c. 1
d. 1/15

Answer 1

15

Explanation:

I took the test and got it right.

Answer 2

Answer: Option 'd' is correct.

Explanation:

Since we have given that

Distance traveled by Jesse's car = d

Number of gallons used = g

The relation between distance and number of gallons used is given by

`d=15g`

We need to find the constant of proportionality in terms of distance traveled per gallon of gas.

So, Constant of proportionality =
`(Distance\ traveled)/(Gallon\ of\ gas)=(d)/(g)`

Since we have

`d=15g\\\\(d)/(g)=(1)/(15)=Constant\ of\ proportionality`

Hence, Option 'd' is correct.
