A train running at the speed of 56 km/hr crosses a pole in 9 sec.

A train running at the speed of 56 km/hr crosses a pole in 9 sec. What is the length of the train?

Answer/Solution

140 m

Steps/Work

Speed = 56 * 5/18 = 140/9 m/sec
Length of the train = speed * time = 140/9 * 9
= 140 m

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

Calculated Answer

140

Step by Step Solution

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

n₀ =	56
n₁ =	9

n₁ * (n₀ * 1000) / 3600
Evaluate n₀ * 1000 = 56000
n₁ * 56000 / 3600
Evaluate 56000 / 3600 = 15.555555555556
n₁ * 15.555555555556
Evaluate n₁ * 15.555555555556 = 140
140
The answer to the problem and the result of n₁ * (n₀ * 1000) / 3600 is 140
