Question

A train is moving with a. speed of 100km/h.Find the distance covered by it in 18 seconds?​

Answer 1

$\Large{\underline{\underline{\bf{Solution :}}}}$

★ Given :

Speed of train (s) = 100 km/h = 27.78 m/s

Time taken (t) = 18 seconds

__________________________

★ To Find :

We have to find the distance(D) traveled by the train.

__________________________

★ Solution :

We know the formula to find the value of

$\Large{\implies{\boxed{\boxed{\sf{Speed = \frac{Distance}{Time}}}}}}$

_______________[Put Values]

$\sf{→ 27.78 = \frac{D}{18}} \\ \\ \sf{→ D = \frac{2778 \times 18}{100}} \\ \\ \sf{→ D = \frac{50004}{100}} \\ \\ \sf{→ D = 500.04} \\ \\ \Large{\implies{\boxed{\boxed{\sf{Distance = 500.04 \: m}}}}}$

$\therefore$ Distance travelled by train is 500 m.

Answer 2

$\large{\underline{\underline{\mathfrak{Answer :}}}}$

• Distance travelled by train is 500 m

$\rule{200}{0.5}$

$\underline{\underline{\mathfrak{Step-By-Step-Explanation :}}}$

Given :

• Speed of train (s) = 100 km/h = 27.8 m/s
• Time interval (t) = 18s

________________________

To Find :

• Distance travelled

Solution :

Use formula for Speed :

$\large{\boxed{\sf{Speed \: = \: \dfrac{Distance}{Time}}}} \\ \\ \implies {\sf{Distance \: = \: Speed \: \times \: Time}} \\ \\ \implies {\sf{Distance \: = \: 27.8 \: \times \: 18}} \\ \\ \implies {\sf{Distance \: = \: 500.4}} \\ \\ \underline{\sf{\therefore \: Distance \: Travelled \: by \: Train \: is \: 500 \: m}}$
