Suppose that while driving a car, the driver suddenly sees an animal standing in the road. The driver's brain registers the information and sends a signal to the driver's foot to hit the brake. The car travels a distance D, in feet, during this time, where D is a function of the speed r, in miles per hour, of the car when the driver se 13 1 the animal. That reaction distance is a linear function given by D(r) =+5. Complete parts a through c below. a) Find the slope of this line and interpret its meaning in this application. Select the correct choice below and, if necessary. fill in the answer boxes to complete your choice. O A. The slope m is For each mile per hour faster that the car travels, it takes feet longer to stop. O B. The slope is not defined. For each mile per hour faster that the car travels, it takes 0 foot longer to stop.
