I got that decimal by dividing 15 minutes by the number of minutes in an hour: Distance traveled (D) is equal to your rate of speed (r) multiplied by the time (t) you traveled that speed.
What makes most distance and rate problems tricky is that you usually have two things traveling at once, so you need to use the formula twice at the same time.
For instance, if the problem says you traveled at 70 miles per hour for 15 minutes, then r = 70 and t = 0.25.
Since the speed is given in miles per hour, the time should be in hours also, and 15 minutes is equal to .25 hours.
