If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is
50/5 = 10 meters per second2
Acceleration is the rate that speed changes.
Acceleration is the time rate of change of speed. Acceleration = speed/time.
The average rate of acceleration is (11/5) = 2.2 m/sec2 .
Acceleration = rate of change of speed = (change of speed) / (time interval) = (25 - 5) / 4 = 20/4 = 5 m/s2
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
Acceleration is the rate of change in velocity (speed) Thus if your speed is constant (50 miles per hour) your acceleration is zero
You haven't mentioned distances or speed or acceleration, so this cannot be answered.

Acceleration
Acceleration is the rate at which speed changes, at least scalarly.
Speed is the rate at which an object is moving, while acceleration is the rate at which an object's speed is changing. Speed is a scalar quantity (only magnitude), while acceleration is a vector quantity (has both magnitude and direction).
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
Acceleration?
Acceleration, it can be both increase and decrease in speed. .
