I found the table that accompanies this problem:
Time(h) 1 2 3 4 5
Distance (mi) 55 110 165 220 275
speed = distance / time
speed = 55/1 = 55 miles per hour
speed = 110/2 = 55 miles per hour
speed = 165/3 = 55 miles per hour
speed = 220/4 = 55 miles per hour
speed = 275/5 = 55 miles per hour
distance = speed * time
distance = 55 miles per hour * 6 hours
distance = 330 miles.
To get the distance traveled, simply multiply the speed by the number of hours spent travelling.
