Question 947569

Bob rides his horse with a constant speed of {{{s=6(mil/h)}}}. 

How long ({{{t}}}) will he take to travel a distance of {{{d=21mil}}}?

{{{d=s*t}}}

{{{t=d/s}}}....plug in given values

{{{t=21mil/6(mil/h)}}}.......simplify

{{{t=cross(21)7cross(mil)/cross(6)2(cross(mil)/h)}}}

{{{t=(7/2)h}}}

{{{t=3.5h}}}

or {{{3h}}}{{{30}}}'
