In that case finding the average speed becomes important to have an estimate of the rate at which the journey is completed. Also we know that Distance average velocity Time. Hence Distance s vu2 v-ua or s v² u²2a.
Average speed 16 ms.
Average speed 2 40 50 40 50 Average speed 4444. Likewise if 320 kilometres are travelled in 4 hours the average speed is also 80 kilometres per hour. Average speed 16 ms. Average speed is measured in units of distance per time and the average speed formula looks like this.
