Its acceleration is 5m/s2.
The formula for acceleration is Final speed - initial speed/time.
So 40m/s - 25m/s is 15m/s.
15m/s divided by 3s is 5m/s2.
Thus the acceleration is 5m/s2

40 m/s subtracted by 25m/s is 15.
15 has to be divided by the additional 3s which is 5
The 5 miles and the seconds left behind are 2
Answer: 5m/s2
