Question 1134543
A boy circles {{{16km/h}}}, and a girl runs {{{4.4m/s}}}. 

Which is faster?

first convert boy's speed in {{{m/s}}}

{{{16km/h}}}...->{{{16km=16000m}}} and {{{1h=3600s}}}

{{{16000m/3600s=4.444444444444444m/s}}}

{{{16000m/3600s=4.4m/s}}}

=> since {{{4.4m/s=4.4m/s}}} means boy circles and girl runs  with same speed, none of them is faster
