Question

find the distance travelled by a body in 5 minutes if it travels with a uniform speed of 20 ms-1​

Answer 1

$\large{\underline{\textsf{\textbf{ Answer :}}}}$

• 6000 m or 6 km.

$\large{\underline{\textsf{\textbf{ Given \: Information :}}}}$

• Speed (v) = 20 m/s

• Time taken (t) = 5 minutes

★ Converting minutes to its SI unit :

$\longmapsto$ 1 minute = 60 seconds

$\longmapsto$ 5 minutes = (60 × 5) seconds

$\longmapsto$ 5 minutes = 300 seconds

$\large{\underline{\textsf{\textbf{ To \: Calculate : }}}}$

• Distance travelled (s)

$\large{\underline{\textsf{\textbf{ Calculation : }}}}$

As we know that,

$\bigstar \: \boxed{\sf {s = vt}}$

• s denotes distance.
• v denotes speed.
• t denotes time.

→ s = (20 × 300) m

→ s = 6000 m

★ Converting metres to km :

→ 1 m = $\sf \dfrac{1}{1000}$ km

→ 6000 m = $\sf \dfrac{6000}{1000}$ km

→ 6000 m = 6 km

Therefore, the distance travelled by the body is 6 km or 6000 m.

★ Distance

• It is the length of the total path covered by the body.
• It is a scalar quantity.
• Its SI unit is metre (m).
• It is denoted by 's'.
• ★ Distance = Speed × Time

★ Speed

• Speed is a scalar quantity.
• Its SI unit is m/s.
• It is denoted by 'v'.
• ★ Speed = Distance/Time

Answer 2

Answer:

Given. u=20m/s

t=5min=5×60s=300s

 Distance travelled S=speedu×timet

=20m/s×300s  

=6000m=6km.
