Question

A football field is about 100 m long. If it takes a person 20 seconds to run its length, how fast were they running ?

Answer 1

Hi Alex, thanks for asking a question here on Brainly!

We can figure how the fast the person is running by dividing the minutes by the seconds. 

$\frac{5m}{sec}$
= $\frac{300m}{min}$
= $\frac{18km}{hr}$

The person was running 18 km/hr. ✅ 

Hope that helps! ★ If you have further questions about this question or need more help, feel free to comment below or post another question and send the link to me. -UnicornFudge aka Nadia.
