Question

How long will a train 245m long take to clear a platform 130m long, if it's speed is 50km/hr

Answer 1

★ GivEn :-

• Length of the Train = 245m = 0.245km

• Length Of the Platform = 130 m = 0. 130km

• Speed of the Train = 50km/h

To FinD :-

• How Long The train took to Cover the platform.

SoluTiOn :-

We are given to Find the Time taken by the Train to cover the platform with respect to speed = 50km/hr.

• The Total Distance = Trains its own distance + Platform distance = 0.245+0.130 = 0.375km

$\bold{ \pink{★Total \: Distance = 0.375km}{} }{}$

• Speed = 50km/hr

$\boxed{ \bold{ \purple{★Time = \frac{Distance}{Speed} }{} }{} }{}$

$\sf{ \bold{★Time = \frac{0.375}{50} = 0.0075hours}{} }{} \\ \\ \boxed{ \bold{ \purple{1 \: hour = 3600seconds}{} }{} }{} \\ \\ \bold{ \pink{★Time = 0.0075 \times 3600 = 27seconds}{} }{}$

$\boxed{ \bold{ \red{★Time \: Taken = 27seconds}{} }{} }{}$

Answer 2

⇒GiVeN :

• → Length Of the Platform = 130 m also written 0. 130km

• → Length of the Train = 245m also written  0.245km

• → Speed of the Train = 50km/h

Step-by-step explanation:

⇒ To FiNd:

• How long will the train took to Cover the platform.

⇒ SoLuTiOn:

• To Find the Time taken by the Train to cover the platform with respect to speed = 50km/hr.

• The Total Distance = Trains its own distance + Platform distance = 0.245+0.130 = 0.375km

• Speed = 50km/hr.

      Time = distance/speed

      = Time = $\frac{0.375}{50}$ = $0.0075 hours$

      = Time = $0.0075$ x $3600$ = 27 seconds

     ∴ $\boxed{\rm{\orange{Answer \longrightarrow }}}$ 27 sec
