So, we need to know what the unit rate. Basically, how many miles in 1 hour is what we are looking for. To do this, we must use the data given. Let's do 2 hours. So, we have to divide 2 hours by 36 miles. 36/2 is 18. So, 18 miles per hour is our unit rate. Now, we need to find how many miles in 8 hours. So, we need to multiply 18 miles (because that's 1 hour) by the number of hours we need, which is 8 in this case. So, 18*8 is equal to 144. So, 144 miles is the distance traveled in 8 hours. Hope this helped!
To solve this, you must follow PEMDAS. First, solve the parenthesis. Because a negative times a positive equals a negative, the product of the fractions is -1/6. Then multiply that by 12. That equals -12/6. This can be simplified down to -2.
