Question

a train is moving with a velocity 120 kmh how much distance does cover in 30 minutes​

Answer 1

$\sf \huge \underline \red { Answer:-}$

1 km

___________________________

$\bf \large \underline {Given:-}$

Velocity of Train (v) = 120 km/h

Time (t) = 30 sec

______________________________

$\bf \large \underline {To \; Find:-}$

Distance Travelled by Train

______________________________

$\bf \large \underline {Solution:-}$

Convert Velocity into m/s by multiplying it by 5/18

⇒ 120 * 5 / 180

⇒ 33.3 m/s

We have formula :-

${\LARGE{\star{\boxed{\boxed{\orange{\mathsf{Velocity \: = \: {\frac{Distance}{Time}}}}}}}}}$

${\large{\implies}{\boxed{\mathsf{\blue{Distance \: = \: Speed \: {\times} Time}}}}}$

________________[Put Values]

⇒ Distance = 33.3 × 30

⇒ Distance = 999 m

⇒ Distance ≈ 1000 m

⇒ Distance = 1 km

$\huge{\mathsf{Distance \: = \: 1 \:km}}$
