Answer:
2.3 m/s
Explanation:
Speed is measured in m/s
7 m / 3 s = 2.3 m/s ( to the nearest tenth)
The average speed of block is 2.33 m/s.
What is the relation between Speed, Distance and Time?
- Speed is distance travelled by time.
- Therefore Speed = Distance / Time
- S = D / T
How to calculate the average speed of the box?
- The distance travelled by a box is 7 m.
- A box is travelling 7 m for 3 second.
So, from the formula,
∴ S = D / T
∴ S = 7 / 3
∴ S = 2.333 m/s
To the nearest tenth, S = 2.3 m/s.
Thus, The average speed of block is 2.33 m/s.
