The formula for average speed also called average velocity in physics and engineering is. Created by Sal Khan. For example if the total distance travelled was 250 miles and the time it took was 5 hours then the average speed was 250 5 50 miles per hour mph.
The formula is s a b 2 displaystyle sfrac ab2 where s.
Now half his journey by train at 60 kmph and remaining journey average speed is 24 kmph. Furthermore this time is elapsed so as to cover that. Set up the formula for average speed given two speeds used for the same amount of time. Average speed is measured in units of distance per time and the average speed formula looks like this.
