Ok so the queistonn is
______ can be either addition subtraction division or multiplication
the answer is <u>an operation symbol</u> since it operates or does things. it's like a verb
This is the way to solve this
Let time = y and speed = x. An inverse variation equation, if time varies inversely with speed, is

. We have y = 2.5 at an x of 48, so we will fill in and solve for k.

. Multiply 2.5 times 48 to get that k = 120. Now we will use that k and a new x of 40 to find a new y, time.

and y = 3. That means it will take 3 hours to travel the distance at 40 miles per hour, which of course takes longer because you're going slower.
