Acar is driving at a speed of 40 mi/h. what is the speed of the car in feet per minute?

The speed of the car per minute is 3,520 feet.

Explanation:
First, we shall convert miles to feet to find how many feet the car can travel in one hour. Since there are 5,280 feet in a mile, 40 x 5,280 = 211,200. So, now we have 211,200 ft/h, but we have to convert to minute instead. Since there are 60 minutes in an hour, 211,200 divided by 60 = 3,520. Therefore, 3,520 ft/min

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
