distance time average speed

calculate equation

To calculate average speed, you need the

following equation:

distance

time

= average speed

Example

Distance: a lap was 300 metres long.

4 x 300 metres = 1,200 metres

Time: Adams completed the 1,200 metres

in 63 seconds

So, average speed: 1,200 = 19.05 metres

63 per second (m/s)

To calculate average speed in kilometres

per hour, use this equation:

Average speed in metres per second (m/s)

x 3.6 = average speed in kilometres per hour

(km/h)

1 Look again at the table in exercise 1.

Calculate the average speed of Gollob, Olsen

and Crump, in m/s.

2 Now calculate the average speed of all the

riders in km/h.​

- Tom, would you like to join one of the youth movements?

- For example?

- What do you think about "The Green Movement"?

- Well, maybe. I like nature. What about you?

- Me too. I'm sure that it cannot protect itself  from such a greedy species as human beings. It needs help.

- Absolutelly agree with you.

- What about another movement? It is called "Young people for Peace"

- Nice name and great goals it has, I guess. Every sensible person on the Earth wants to live in peace. Me too.

- That's right. I've heard about one more movement - The Stay Healthy Monement.

-Oh, souds great. I'd like to to take part in it. I'm for healthy life. I'm really against smoking, drinking, drugs and so on.
