The area under a speed-Time graph is represented by the unit: a- m2 b- m c-m3 d- 1/m
Answers
Answer:
it should be b) m
Explanation:
Since rate of change in distance over time is speed , Area under speed - time graph will give us distance . whose unit is metre . the area under speed-time graph is the distance travelled by the body within that time period or with the speed...it would be displacement if speed was velocity

Therefore the unit of the area under a speed-time graph is 'meter'. ( Option-b )
Given:
The area under a speed-time graph is given.
To Find:
The unit of the area under a speed-time.
Solution:
The given question can be solved as shown below.
The area under a speed-time graph = Speed × Time
⇒ Speed = Distance / Time ⇒ Distance = Speed × Time
So the area under a speed-time graph ( Speed × Time ) gives the distance.
Hence the units of Distance are meters or centimeters.
Therefore the unit of the area under a speed-time graph is 'meter'.
