Question 1202575
That variation or proportionality constant is called speed.


Question was, how far in 14 hours.


{{{14*hours*((910*miles)/(13*hours))}}}

{{{(14*910)/13}}}{{{miles}}}



If you are required, you can go like this:
d, distance traveled
t, time spent traveling
k, proportionality constant,
{{{d=kt}}}
and use that...
