Question 653648
let distance be {{{d}}}, speed {{{v}}} and time {{{t}}}

as you know, {{{d=v*t}}}...

given:
 
Ben can run {{{v=((1/6)*mil)/2min=(1mil/12min)}}}  

How long should it take (nee to find {{{t}}}) her to run {{{d=2mil}}}


{{{d=v*t}}}....solve for {{{t}}}


{{{2mil/(1mil/12min)=t}}}...plug in given values for {{{d}}} and {{{v}}} 


{{{2cross(mil)/(1cross(mil)/12min)=t}}}


{{{2/(1/12min)=t}}}


{{{2*12min=t}}}


{{{24min=t}}}
