Calculating Deceleration Rate of a Car

I apologize for my ignorance, I'm an extreme newbie in physics.
Is it possible to determine the deceleration rate of a car only with following information?

initial velocity = 60mph (96km/h)
final velocity = 0mph (0km/h)
distance = 146ft (44.5m)

if so, how many distance would it take to stop from 60km/h (37.5mph)?

Thank you

v=Final velocity
u=initial velocity
a=acceleration
s=displacement.

do a search for Newton's laws of motion. they are probably the most well known equations for scientists and engineers and worth remembering. there are a few other derivations than the one that rock freak has given you.
