A 240 m long train passes a platform in 45 sec while it passes a signa

1.	A 240 m long train passes a platform in 45 sec while it passes a signal board in 16 sec. What is the length of the platform?1. 435 m2. 440 m3. 450 m4. 455 m5. 550 m
Answer» Correct Answer - Option 1 : 435 m Given: Length of the train = 240 m Time taken on crossing the platform= 45 sec Time taken to pass a signal board = 16 sec Formula Used: Speed of train = Distance traveled to cross the signal / Time taken Calculations: According to the formula, Speed of train = Distance traveled to cross the signal / Time taken ⇒ 240/16 m/s ⇒ 15 m/s Let the length of the platform be x. Then, (x + 240)/45 = 15 ⇒ x + 240 = 675 ⇒ x = 435 m The length of the platform is 435 m.

A 240 m long train passes a platform in 45 sec while it passes a signal board in 16 sec. What is the length of the platform?1. 435 m2. 440 m3. 450 m4. 455 m5. 550 m

Answer» Correct Answer - Option 1 : 435 m

Given:

Length of the train = 240 m

Time taken on crossing the platform= 45 sec

Time taken to pass a signal board = 16 sec

Formula Used:

Speed of train = Distance traveled to cross the signal / Time taken

Calculations:

According to the formula,

Speed of train = Distance traveled to cross the signal / Time taken

⇒ 240/16 m/s

⇒ 15 m/s

Let the length of the platform be x.

Then, (x + 240)/45 = 15

⇒ x + 240 = 675

⇒ x = 435 m

The length of the platform is 435 m.
