Sure it is.

The faster you run, the quicker you'll finish the race.

So... to put that in mathematical terms...

The time it takes you to run a 100m race varies inversely with the speed you run.

Put it in a formula...

T = K/S

Where: T is the time taken to complete the race

K is our constant (the 100m distance to cover)

& S is the runner's speed

Let's use some values

We already know that K is 100 (because its a 100 meter race)

Suppose our racer runs at 0.5 meters per second, so S, our speed is 0.5

Then plug in the values & solve

T = 100/0.5

So T = 200

Meaning it will take the racer 200 seconds to complete the race

Alternatively, suppose the racer runs at 2 meters per second

T = 100/2

So T = 50

Meaning it will take the racer racer 50 seconds to complete the race

Notice how the time taken was shorter?

Course it was!

Cause the racer was running faster.
