Take away the date of the past event from the current date.
time = distance ÷ speed
Speed times Time = Distance
Speed = distance divided by time
Distance divided by speed is used to calculate time.
SPEED = DISTANCE divided by TIME
Speed = Distance divided by Time
You would have a very tough time, because that isn't the formula to calculate work. (distance) divided by (time) is the formula to calculate speed. The formula to calculate work is: (force) multiplied by (distance).
time=distance divided by speed
time=distancedividedby speedbecause speed= distance divided by time and distance= speed*time
Average speed during the time = (distance) divided by (time for that distance)
You can calculate a speed by dividing a distance by the time it takes to cover that distance. If you want the instantaneous speed (for situations of variable speed), you need to calculate the distance and time for a fairly short time interval (ideally, the limit, when the time approaches zero).
Distance = time x speed
