A train running at the speed of 60 km/hr crosses a pole in 21 sec.

A train running at the speed of 60 km/hr crosses a pole in 21 sec. What is the length of the train?

Answer/Solution

350 m

Steps/Work

Speed = 60 * 5/18
= 50/3 m/sec
Length of the train
= speed * time
= 50/3 * 21
= 350 m

A train running at the speed of km / hr crosses a pole in sec. What is the length of the train?

Calculated Answer

350

Step by Step Solution

In order to solve problem, you must evaluate n₁ * (n₀ * 1000) / 3600.

n₀ =	60
n₁ =	21

n₁ * (n₀ * 1000) / 3600
Evaluate n₀ * 1000 = 60000
n₁ * 60000 / 3600
Evaluate 60000 / 3600 = 16.666666666667
n₁ * 16.666666666667
Evaluate n₁ * 16.666666666667 = 350
350
The answer to the problem and the result of n₁ * (n₀ * 1000) / 3600 is 350
