A hyena can run 1/4 of a mile in 22.5 seconds. At this rate, which equation can be used to determine how fast a hyena runs in miles per hour?

If we know the distance someone or something ran and how long it took them to run, then we know their rate.

Because rate can be defined as [tex]\frac{d}{t}[/tex].

We want the answer to be in miles per hour, so convert 22.5 seconds into hours by dividing 22.5 by 3600.

22.5 / 3600 = 0.00625

And because we have a decimal and a fraction, it is best to convert the fraction into a decimal so all units are the same.

1 / 4 = 0.25

Plug in the values.

0.25 / 0.00625 = 40

So, the hyena would be running at 40 mph.

The equation to determine how fast the hyena runs in miles per hour is;

  • Speed = (3600d/t) miles per hour

According to the question;

The hyena can run 1/4 miles in 22.5 seconds.

We must remember that the hyena's speed is given as;

  • Speed = d/t

  • where d = no. of miles ran

  • and t = time taken.

  • Distance = 1/4 miles = 0.25 miles.

Time taken = 22.5 seconds = 22.5/3600 hours.

In essence, The equation to determine how fast the hyena runs in miles per hour is;

  • Speed = (3600d/t) miles per hour
