Additional Information :
What is Speed ?
➜ The rate of change of position of an object in any direction.
What is the formula of Speed ?
➜
Where,
- s is the speed
- d is the distance

➜ CGS system → cm/s
➜ SI system → m/s
How many types of Speed ?
➜ There are five types of speed and they are:
- Uniform speed
- Variable speed
- Average speed
- Instantaneous speed
Uniform speed: A object is said to be in uniform speed when the object covers equal distance in equal time intervals.
Variable speed: A object is said to be in variable speed when the object covers a different distance at equal intervals of times.
Average speed: Average speed is defined as the uniform speed which is given by the ratio of total distance traveled by an object to the total time taken by the object.
Instantaneous speed: When an object is moving with variable speed, then the speed of that object at any instant of time is known as instantaneous speed.
Given :
- Distance is 15 m
- Time is 5 seconds
To find :
- Speed
According to the question,
According to the formula we will put the value,
.°. The speed is 3 m/s...
