Question

a1 An object is moving in speed 20 m/s and covers 10 mitre distance. what time is required by an object to cover that distance ​

Answer 1

Given :

• Speed of an object = 20 m/s

• The distance covered by the object = 10 m

To find :

• Time required to cover the distance of 10 m

Solution :

Formula to find the time :-

$\boxed{\bf\red{Time = \dfrac{Distance}{Speed}}}$

Substituting the given values :-

$\implies\sf Time = \dfrac{10}{20}$

$\implies\sf Time = \dfrac{1\not0}{2\not0}$

$\implies\sf Time = \dfrac{1}{2}$

$\implies\sf Time = 0.5$

Therefore, the time required to cover the distance of 10 m = 0.5 seconds

Extra Information :

★ Distance is the path travelled by an object.

• It's S.I. unit m.
• It's CGS unit is cm.
• It is a scalar quantity as it doesn't have an direction but only magnitude.
• Formula to find distance = Speed × Time

★ Speed is rate at which an object travels.

• It's S.I. unit is km/h.
• It's CGS unit is m/s.
• It is a scalar quantity as it doesn't have any direction but only magnitude.
• Formula to find speed = Distance ÷ Time
