Acceleration and speed? Physics/maths? Pls help...?

How would you go calculate this: 1) A rocket has an average speed of 5000 km per hour. Travelling at this speed, how long would it take the rocket to travel 12,740km? 2 From take off, the rocket can get upto 2 km/s in 14 seconds. What's the acceleration of the rocket in m/ss? ... show more How would you go calculate this:

1) A rocket has an average speed of 5000 km per hour.
Travelling at this speed, how long would it take the rocket to travel
12,740km?

2 From take off, the rocket can get upto 2 km/s in 14 seconds. What's the acceleration of the rocket in m/ss?

I know the units for acceleration
are metres per second squared,
but my computer doesn't do the
little '2' for squared.

I'm NOT asking people to do my homework for me, i'm just asking
1) The sums i would need to do to calculate these things
and
2) Why?

Thanks very much =]
