Provide an appropriate response.The amount of time, t, it takes to travel a distance, d, at a speed, r, is given by the following: t = 
. If you have to travel 500 miles and you want to know how long it will take, what values of r are meaningless?
What will be an ideal response?
r can't be zero because you can't divide by zero. (If you travel 0 mph you will never get there). Negative values of r also don't make sense. They would give negative time answers and time doesn't go backwards.
