Acceleration= distance / velocity squared
You use the equation: acceleration=change in velocity/time interval a = 60 / 10 a = 6
Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
If the car doesn't change direction during that 100 seconds, then it's zero. If the car's direction changes, then the acceleration isn't zero, but the question doesn't give any information from which to evaluate it.

Acceleration= distance / velocity squared
Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.
If velocity is steady and doesn't change, then there is 0 acceleration.
Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.

The answer is very simple. The words "constant velocity" are the definition of zero acceleration.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
6km/h/s Increase of 60, divided by the number of seconds.
velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.
