Initial velocity, u = 80 miles/h = 8/6 miles/sec
Final velocity, v = 80 miles/h = 8/6 miles/sec
Here "u" and "v" are same because the car is travelling at constant speed which means that the speed does not change at all.
Time, t = 10 seconds
Acceleration, a = (v - u)/t
a = (8/6 - 8/6)/10 = 0/10 = 0 m/s^2
Final velocity, v = 80 miles/h = 8/6 miles/sec
