Question 893755
How many hours did they drive on the first day? 
I'll assume they drove at the same rate every day.

Rate*Time=Distance
Time=Distance/Rate
{{{T=3000/R}}}
In this case,
{{{T=9D}}} since they only drive 9 hours per day.
{{{9D=3000/R}}}
{{{D=1000/(3R)}}}
So if they drive 33.33 miles per hour,
{{{D=1000/(3(33.33))=10}}}, it would take them 10 days.
