Question

a player completes its 100 metre race in 12s its average speed will be..​

Answer 1

Answer:

Average speed = Total distance travelled / total time taken

= 100 / 12

Average speed ( v ) = 8.33 m / s

Answer 2

Given

A player completes its 100 metre race in 12 s

To Find

Average speed

Solution

We know that

$\sf \longrightarrow v=\dfrac{s}{t}$

Here

• v = Speed
• s = Distance
• t = Time

Units

• v = metre per second (m/s)
• s = metre (m)
• t = second (s)

According to the question

We are asked to find average speed

Therefore

We must find "v"

Given that

A player completes its 100 metre race in 12 s

Hence

• s = 100 m
• t = 12 s

Substituting the values

We get

$\sf \longrightarrow v=\dfrac{100}{12} \ m/s$

Therefore

$\sf \longrightarrow v \approx 8.33\ m/s$

Hence

Average speed = 8.33 m/s
