If I drive a rental car .45miles at 25.00 dollars per day and my other rental car .25miles at 40.00 per day how many miles must i drive for them to cost the same

You are driving your rental cars only about 1/2 mile and the other at 1/4 mile?

I would just walk the distance.

Check your typing or the wording of the question.

The answer is to drive the $40 per day car .72 miles per day.

Car 1 is getting 0.45 miles (mi) per (/) 25 Dollars (USD). To simplify divide 0.45 mi by 25 USD and you could state:
Car 1 is getting 0.018 mi/1USD

Car 2 is getting 0.25 mi /40USD
or Car 2 is getting 0.00625 mi /1USD

How much more does car 1 get than Car 2?
0.018mi - .00625 mi = 0.01175 more miles dollar.

So to get equal value out of both cars I would drive Car 2 the .25 miles a day plus the difference in value from car 1:
0.25 mi + (0.01175 mi X 40 USD) = 0.72 miles.

You could also just divide 0.018/0.00625=2.88
2.88x.25=0.72

Math is fun. Different ways to get the same right answer.

To find the number of miles you must drive for the two rental cars to cost the same, we can set up an equation.

Let's assume the number of miles you need to drive for them to cost the same is 'x'.

The cost for the first rental car is given by: 25.00 per day

The cost for the second rental car is given by: 40.00 per day

Now we can write the equation:

25.00 * 0.45 = 40.00 * x

To solve this equation, we can simplify it:

11.25 = 40x

Now, we can solve for 'x' by dividing both sides of the equation by 40:

x = 11.25 / 40

Calculating this, we find:

x = 0.28125

Therefore, you would need to drive approximately 0.28125 miles for the two rental cars to cost the same.
