Acceleration = [ (final velocity) - (initial velocity) ] / (time elapsed)
Make sure you have "like" units. In this case, convert the 2.5 min to hrs and plug everything into the equaiton.
If an airplane is traveling at 900 km/hr and slows to 450km/hr in 2.5 minutes. What is the plane's acceleration?

a = [450km/hr - 900 km/hr]/2.5 minutes
a = [-450km/hr]/2.5 minutes
a= [-450km/hr]/0.416 hrs
a = -10817.31km/hr2
is that correct?
