Answer:

\bold{t = f(s) = \dfrac{6.2}{s}}

Step-by-step explanation:

Given that distance is 10,000 meter or 6.2 miles.

Time taken is t minutes.

Average speed is s miles/minutes

To find:

Equation to determine time 't' as a function of average speed 's' = ?

t is in minutes and

s is in miles/minute

Solution:

First of all, let us have a look at the formula for Average Speed:

\text{Average Speed} = \dfrac{\text{Total Distance Traveled}}{\text{Total Time Taken}}\\\Rightarrow \text{Total Time Taken} = \dfrac{\text{Total Distance Traveled}}{\text{Average Speed}}\\

Now, we are given that Time, t should be in minutes and

Average speed, s must be in miles per minute

That means, we must have distance in miles.

Putting all the values in above formula.

So, the formula or equation becomes:

t = \dfrac{6.2}{s}

Therefore the equation to find time, t in minutes as a function of Average Speed, s is given as:

\bold{t = f(s) = \dfrac{6.2}{s}}

Answer:

b) f(x) = x + 6

Step-by-step explanation:

The coordinate (0, 6) makes the y-intercept = 6. Only one of these functions has that intercept: f(x) = x + 6. If you plug in each coordinate the outputted y-value matches up, making this the right answer.
