Question

an autorickshaw covers a distance of 380 km in 8 hours . Calculate the speed of the auto in 1) km/h 2)m/s​

Answer 1

distance covered by auto = 380 km

time take to cover the distance = 8 hours

speed of any object = distance/time

so speed of the auto :

1) km/h = 380/8

= 47.5 km/h

2) m/s = 47.5*5/18

= 13.19 m/s

⇝Solution :-

❒ We know :

${\large{\red{\bigstar \: \: {\orange{\underbrace{\underline{\blue{\bf{Speed = \frac{Distance}{time} }}}}}}}}}$

❒ Speed in km/h :

✏ Values :

• ➵ Speed = ?
• ➵ Distance = 380 km
• ➵ Time = 8 hours

✏ Speed :

${\longrightarrow{\sf{ \: \: \: \: \: \: speed = \frac{380}{8} }}}$

${\longrightarrow{\sf{ \: \: \: \: \: \: speed = {\cancel\frac{380}{8} }}}}$

${\large{\red{:{\longmapsto{\underline{\tt{47.5 km/h}}}}}}}$

❒ Speed in m/s :

✏ Converting the values :

• ➵ Speed = ?
• ➵ Distance = 380 × 1000 = 380000 m
• ➵ Time = 8 × 60 × 60 = 28800 s

✏ Speed :

${\longrightarrow{\sf{ \: \: \: \: \: \: speed = \frac{380000}{28800} }}}$

${\longrightarrow{\sf{ \: \: \: \: \: \: speed ={\cancel \frac{380000}{28800} }}}}$

${\large{\red{:{\longmapsto{\underline{\tt{13.194 \: m/s}}}}}}}$

❒ Hence :

${\large{\purple{\underline{\pink{\textbf{Speed km/h = 47.5 km/h}}}}}}$

${\large{\purple{\underline{\pink{\textbf{Speed m/s = 13.194 m/s}}}}}}$
