Question 1065227

700 mph is the rate
3000 miles is the distance

—
 {{{ d = r*t }}}
 where d = distance
            r = rate
            t = time
—
 Solving for t gives:   {{{ t = d/r }}}

 You can now plug in the numbers (always make sure the unit are compatible first).  In this problem you have mi/hr and mi, so you will get an answer in hrs.
