Question 914941
{{{d=335ft}}} 

{{{s=40(mil/h)}}}

find: {{{t}}}

{{{d=s*t}}}

{{{t=d/s}}}  convert {{{d=335ft}}} into miles: 


{{{1Foot = 0.00018939394Mil}}}

{{{d=335ft=335*0.00018939394Mil=0.0634469699Mil}}}

then

{{{t=0.0634469699crossMil/(40(cross(mil)/h))}}} 

{{{t=(0.0634469699/40)h}}} 

{{{t=0.0015861742475h}}}

{{{t=0.0015861742475*60min}}} 


{{{t=0.09517045485min}}} 


{{{t=0.09517045485*60Sec}}} 


{{{t=5.710227291Sec}}} round it
