Use the maths symbols icon to write the equation. Pressing the slash "/" in this mode will program a division line in your formula.

Usain bolt runs 100 metres in 9.58 seconds. If hypothetically he was able to maintain the same average speed, how long would it take him to run a 42 km marathon to the nearest hour?

You use a video to create a graph of the position of Usain Bolt from the starting line vs time from the start of the race, and you get the graph shown below.You use the graph to calculate what his position would have been at a time of 6 s. This process is known as:Question 7Select one:a.Extrapolationb.Interpolationc.Linearisationd.Estimatione.Analysis

The speed of a runner increased steadily during the first three seconds of a race. Her speed at half-second intervals is given in the table.
