Question

Ram covers a distance of 10 m in 5 a and shyam covers a distance of 21 m in 21 m in 7s .who is faster by how much? ​

Answer 1

Given:

• Ram covers a distance of 10 m in 5sec

• shyam covers a distance of in 21 m in 7sec

To Find:

• Who is faster and by how much?

Solution:

${\mathfrak{ \purple{ \underline{G iven \: clues: \dag }}}}$

• Distance Covered by ram is 10m
• Tike taken by ram is 5sec

• Distance Covered by shayam is 21m
• Time taken by shayam is 7sec

⇨ Analysis:

➼ As we have to check who's faster so we have to calculate the speed of ram and shayam.

${ \mathfrak{ \purple{ \underline{ Aa \: we \: know \: that} : }}}$

$\longrightarrow\blue{ \underline{ \boxed{ \pink{ \mathfrak{ \: speed \: = \frac{distance}{time} }}} \bigstar}}$

➸ Let's calculate their speed now.

Speed of Ram :

$\longrightarrow \sf \: speed \: = \dfrac{distance}{time}$

➼ Let's substitute the given values now,

↦ $\sf \: speed \: = \cancel \dfrac{10m}{5s}$

↦ $\sf \: speed \: = 2m \: per \: second \bigstar$

❶ hence, the speed of ram is 2m/ per second .

Speed of shyam :

$\longrightarrow \sf \: speed \: = \dfrac{distance}{time}$

➼ Let's substitute the given values now,

↦$\sf \: speed \: = \cancel \dfrac{21m}{7s}$

↦$\sf \: speed \: = 3m \: per \: sec \bigstar$

❷hence, the speed of shyam is 3m/second

$\blue{ \underline{ \boxed{ \blue{ \mathfrak{ hence \: forth \: the \: sped \: of \: shyam \: is \: more \: by \: 1m \: per \: sec}}}}}$

$\orange{\longrightarrow \bf \: distance = speed \times time \bigstar}$

$\orange{ \longrightarrow \bf \: time = \dfrac{distance}{speed} \bigstar}$

 ✦ Stranded Units :

• Speed – m / sec

• Time – second

• Distance – meter
