To calculate the gradient of a straight-line graph: Choose two points ... 10 seconds and so to work out the average speed use: Average speed = \(\frac{distance}{time}\). Distance = 7 m.

An athlete completing 100 metres in 10 seconds has an average speed of 10 metres per second (m/s). The athlete travels 10 metres every second. Use ... Practise calculating speed, distance and ...

In one dimension, the average velocity is simply the change in position over the change in time: So, for a race like this you can calculate ... graph is -5.189 m/s. So, Shanteau starts with a ...

In my recent post about calculating ... use the moons of Jupiter as his accurate clock---and this is where he found a problem. The only way you could use the distance method for finding the speed ...
