Acyclist traveled 15 kilometers per hour faster than an in-line skater. in the time it took the cyclist to travel 12 kilometers, the skater had gone 6 kilometers. find the speed of the skater.

The speed of the skater is 15 kilometers per hour.

Step-by-step explanation:

Let x be the rate of the skater.

Then the rate of the cyclist is x+15.

Let t represents time, so we get two equations:

(x+15)t = 12 and xt = 6

Now, solving for t;

and

As t is the same for the skater and the cyclist, we will equate both the equations now.

Solving for x;

=>

=>

=>

x = 15

Hence, the speed of the skater is 15 kilometers per hour.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
