Need help on a physics question?

Question

an automobile, starting from rest, accelerated uniformly for 10 seconds and increases its velocity to 20 miles per hour. Calculate the acceleration of the automobile.

I did
a=change in v/t
a=20-0/.00277
and got a=7200

apparently the answer is 7190 ?
I can't get that number. what am i doing wrong?
