Question

After receiving new engines in 1987, the queen elizabeth 2 moves 49.5 feet for every gallon of fuel that it burns. Previously, it moved 36 feet per gallon. Write an equation and describe the proportionality.

Answer 1

Given:

Queen Elizabeth 2 moves 49.5 feet for every gallon of fuel that it burns.

Let the number of gallons = G

And, let the number of feet = D

Previously, it moved 36 feet per gallon.

We will compare the values of D and G

So,

G :

1 : 49.5

1 : 36

As shown for the same number of gallons D in the second time is greater than D in the first time

So, we have a proportional relationship

so, the equation will be:

$D=k\cdot G$
