A bicyclist starts from at an acceleration of (1.2m/s^2) (1.2 meter per second squared).. how far must he travel to reach a speed of 7m/s.(that 7 meters per second..not second squared)..Can you show how to do this, what is needed to know?

Do you know the definition of acceleration?
Basically, we can say in algebra that:
$\displaystyle a = \frac{v - u}{t}$
That is acceleration (constant) is the rate of change of velocity.
From there, you can derive other formulae that can help you better than others depending on what is given.
