what determines car speed
Speed = Distance Ã· Time or s = d/t For example, the speed of a car that traveled 40km in 30 minutes: s = 40/30 minutes s = 40/0.5 hours s = 80km/h Remember, if the time is giâ¦ven in minutes you must remember to convert this to hours by dividing the time by 60, e.g. 30 mins = 0.5 hours.
