Question

a. Represent the speed of a runner as a function of the time it takes to run
100 meters in the track.
Let x represent the time it takes to run 100 meters.​

Answer 1

Answer:

the required function is f(x) =100/x(speed =distance /time

Answer 2

Hint:

If $t$ be the time to run a path measuring $d$, then the speed $s$ is given by

$\quad Speed\:(d)=\dfrac{Distance\:(d)}{Time\:(t)}$

Step-by-step explanation:

Given, $x$ represents the time to run $100$ meters.

We have to find the function for speed.

Using the relation between distance, time and speed, we can write

$\quad speed=\dfrac{distance}{time}$

$\Rightarrow speed=\dfrac{100}{x}$

If we consider $speed\:(s)=f(x)$, then

$\quad f(x)=\dfrac{100}{x}$

Final answer:

Function for time is $f(x)=\dfrac{100}{x}$.
