I drove to the beach at a rate of 40 miles per hour. If I had driven at a rate of 30 miles per hour instead, then I would have a
Sedaia [141]

Answer:

40 miles

Step-by-step explanation:

Let's set <em>x</em> to the number of miles driven, and <em>t</em> to the number of hours it took to drive.

We know that 40<em>t</em> is equal to <em>x</em>.

We also know that 40<em>t</em> is equal to 30(<em>t</em> + 1/3).

Solve for t:

40t = 30(t+1/3)

40t = 30t + 10

Subtract 30t from both sides:

10t = 10

Divide 10 from both sides:

t = 1

40t = 40 x 1 = 40 miles
