5 hours is equals to 15mph, as you can see, if you multiply every step, is equals to 75, (75x1=75, 25x3=75, 20x3.75=75, etc.)

Step-by-step explanation:
Question:
What is 3(x + 2) - 2(x + 1)?
Steps:
When you solve this type of equation always use the distributive property formula to solve this equation!
Formula: a(b + c) = ab + ac
So, what is 3(x + 2) ?
Also, what is -2(x + 1)?
Then, put it back into the equation for you to solve this problem.
So, this would be the new equation:
3x + 6 - 2x - 2
Then, what you want to do is put variables next to each other and the numbers next to each other so it will be easier to simplify:
3x - 2x + 6 - 2
Then, simplify:
x + 4 is the answer!
Since 3x - 2x = x and 6 - 2 = 4
