Answer 2

$\underline{\underline{\bigstar\;\frak{Solution\;:}}}$

⠀

• Here, we are given that a scooter travels a distance of 3 km in 5 minutes. We've been asked to calculate it's speed in cm/sec and m/sec.

⠀

⟩ In order to calculate the distance travelled in different units, we firstly need to convert the unit of distance and time according to it. Distance travelled:

⠀

• Distance travelled by scooter (in meters) is 3000 metres.
• Distance travelled by scooter (in centimetres) is 30,00,000 cm or 3,000× 100 cm.

Time taken:

• Time taken by scooter to travel the given distance (in seconds) is 300 sec.

⠀

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀⠀

( a ) Speed of scooter in cm/sec:

$\\\longrightarrow\quad\sf{Speed=\dfrac{Distance}{time}}$

⠀

$\\\longrightarrow\quad\sf{Speed=\dfrac{3000\times 100}{300}}$

⠀

$\\\longrightarrow\quad\underline{\boxed{\pmb{\frak{Speed=1000\; cm/s}}}}\; \bigstar$

⠀

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀⠀

( b ) Speed of scooter in m/sec

$\\\longrightarrow\quad\sf{Speed=\dfrac{Distance}{time}}$

⠀

$\\\longrightarrow\quad\sf{Speed=\dfrac{3000}{300}}$

⠀

$\\\longrightarrow\quad\underline{\boxed{\pmb{\frak{Speed=10\; m/s}}}}$

⠀

❝Henceforth, the speed of scooter in cm/sec and m/sec are 1000 cm/s and 10 m/s respectively.❞
