Question

As the earth rotates, it travels a distance of 80 miles in 5 minutes. At this constant rate, which equation best represents y, the total distance the earth travels in x minutes?

Answer 1

y=16x

Explanation:

So, you are given the equation as if y=total distance the earth travels in x minutes. If you are given that you travel 80 miles in 5 minutes, you can plug these value into the variables they are representing and solve for the constant.

Visual:

y=xk y=miles x=minutes k=constant

Plug in your values and you get:

80=5k

Now, you solve for k by diving 5 on both sides, which leaves you with k=16.

Now you plug your value for k into the original equation, leaving you with y=16x
