Question

A train travels a distance of 100 meter
in 5 seconds. What will be its speed

Answer 1

Answer:

s=ut+(1/2)at

2

100=(1/2)×a×5

2

a=8 m/s

2

v=u+at

v=0+8×5=40ms

.

Answer 2

Answer:

20 m/s

Explanation:

As per the provided information in the given question, we have :

• Distance covered by the train (s) = 100 m
• Time taken (t) = 5 seconds

We are asked to calculate speed (v).

$\longrightarrow$ Speed = Distance ÷ Time

$\longrightarrow$ Speed = 100 m ÷ 5 s

$\longrightarrow$ Speed = 20 m/s

Therefore the speed of the train is 20 m/s.

More Information :

About speed :

• Speed is defined as distance covered per unit time.
• It is a scalar quantity.
• Its SI unit is m/s.
• It is denoted by v.

About distance :

• Distance is the total length of the path covered by the body.
• It is a scalar quantity.
• Its SI unit is m.
• It is denoted by s.
