13pts ! a car travels at a speed of s miles per hour. it covers 126 miles in 3 hours. the equation that can be used to find the value of s is (blank) × s = (blank). the speed of the car is (blank) miles per hour.

3 X S = 126

Step-by-step explanation:

because the variable (s) is speed then we must know that 126 is tyhe total that it is driving in 3 hours so 3 time S is 126

The speed of the car is 42 miles per hour

Step-by-step explanation:

Step 1:

(Blank) x s = (Blank)

Let us evaluate this. Something times s miles per hour is going to gives us? 126 miles. So, our second blank would be 126 since that's our total:

(Blank) x s = 126

Step 2:

On the other hand, our first blank would be 3. Why? Because that's the amount of time it takes us to go 126 multiplied by s miles per hour; Our new equation is:

3 x s = 126

Step 3:

We can simplify this equation to:

3s = 126

Step 4:

We now have a one step equation. Divide each side by 3 to get s by itself.

Step 5:

We end up getting:

s = 42

That means that the car is traveling at 42 miles per hour. If the car continues at that rate for 3 hours, the car would have traveled 126 miles.

Hope this helps!
