You are expected to already know that:
d = rt
where
d is the distance
r is the rate or speed
t is the time
.
In your problem, they are asking you to derive an equation for "distance" given that the "rate" is x mph and the time is 2 hours. We simply plug it all into:
d = rt
distance = x(2)
or
distance = 2x (miles)
