A train running at the speed of 36 km/hr crosses a pole in 9 seconds.

A train running at the speed of 36 km/hr crosses a pole in 9 seconds. Find the length of the train?

Answer/Solution

90 meter

Steps/Work

Speed = 36*(5/18) m/sec = 10 m/sec
Length of Train (Distance) = Speed * Time
(10) * 9
= 90 meter

A train running at the speed of km / hr crosses a pole in seconds. Find the length of the train?

Calculated Answer

90

Step by Step Solution

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

n₀ =	36
n₁ =	9

n₁ * (n₀ * 1000) / 3600
Evaluate n₀ * 1000 = 36000
n₁ * 36000 / 3600
Evaluate 36000 / 3600 = 10
n₁ * 10
Evaluate n₁ * 10 = 90
90
The answer to the problem and the result of n₁ * (n₀ * 1000) / 3600 is 90
