== I'm pretty sure the formula for distance is: D== rt (Distance= rate x time) == The formula for distance is: speed x time.
Time equals Distance divided by rate
rate = distance / time (r= d/t)
Our formula is Distance = Rate * Time Distance = 0.1 miles Rate = 70 mph Time = unknown Solve formula for Time Distance/Rate = Time So, 0.1 miles/70 mph or 1/700 hours. Approximately 5.14 seconds
Generally: RATE = DISTANCE / TIME -or- DISTANCE = RATE * TIME -or- TIME = DISTANCE / RATE qed
