Question 633561


If the distance between his work and home is {{{d=30 mil}}}, and if Mark leaves home at 9am and arrives at work at 9:45am, the time {{{t}}} is {{{45min}}}.

To find how fast did he travel, calculate speed (velocity) {{{v}}} by using a formula 

{{{v=d/t}}}

{{{v=30mil/45min}}}.......you need a time in hours....{{{45min=0.75h}}}

{{{v=30mil/0.75h}}}

{{{v=40mph}}}
