There are two race cars. the sum of their fastest speed is 50o.3 miles per hour. If the If the speed of one of the cars is 2.8 mph faster then the other car, what are the speeds of each car?

What is MCC. I never heard of that school subject before.

If the speeds are x and y then

x+y = 500.3
y = x+2.8

Now just substitute in for y, figure x, then get y.

To find the speeds of each car, we can set up a system of equations based on the given information.

Let's assume the speed of one car is x mph. Since the other car is 2.8 mph faster, the speed of the other car would be (x + 2.8) mph.

Now, we can set up the equation based on the sum of their speeds:

x + (x + 2.8) = 500.3

Simplifying the equation, we have:

2x + 2.8 = 500.3

Subtracting 2.8 from both sides, we get:

2x = 497.5

Dividing both sides by 2, we find:

x = 248.75

So, one car is traveling at a speed of 248.75 mph.

To find the speed of the other car, we can substitute this value of x into one of our equations, for example:

Speed of the other car = 248.75 + 2.8 = 251.55

Therefore, the two cars are traveling at speeds of 248.75 mph and 251.55 mph.
