The equation d=rt is used to calculate distance, rate, or time, where d is the distance (in miles), r is the rate (in miles per hour), and t is the time (in hours). Consider the statements below that describe the driving rates for three people. Graph the equation that represents the rate of the fastest person. Braylon drives at a rate of 50 miles per hour. Kiko drives for 9 hours and goes 405 miles. Presley drives 385 miles in 7 hours.
