Fred can run 12 miles in 1 hour and can bike 30 miles in 2 hours. what percent of fred’s average biking speed is his average running speed?

first thing you have to do is find the rate for the bike so you divide 30 by 2 and you get 15 after you do that you make a problem to find the percentage so you take x/100 and 12/15 then you take 12 times 100 and that gives you 1200 then you divide by 15 and get 80. So the answer is 80%

Step-by-step explanation:

First, create an equation for the price of the car for both dealerships:

Dealership A:   y = 150x + 2500

Dealership B:   y = 125x + 3000

where y is the total cost of the car and x is the number of months that have passed.

You know that y is equal to "150x + 2500" AND y is equal to "125x + 3000," so "150x + 2500" must be equal to "125x + 3000"

Now, just solve for x to find the number of months at which the total amount paid would be the same for both dealers:

So, after 20 months, the price of the car at both dealerships is the same. To find that price, just plug in 20 for x in one of the equations (because x was the number of months):

So, the car costs the same after 20 months, $5500 at either dealership.
