A train running at the speed of 70 km/hr crosses a pole in 36 seconds.

A train running at the speed of 70 km/hr crosses a pole in 36 seconds. What is the length of the train?

Answer/Solution

700

Steps/Work

Speed=(70 * 5/18) m/sec = (175/9) m/sec Length of the train = (Speed x Time) = (175/9 * 36) m
= 700 m.

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

Calculated Answer

700

Step by Step Solution

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

n₀ =	70
n₁ =	36

n₁ * (n₀ * 1000) / 3600
Evaluate n₀ * 1000 = 70000
n₁ * 70000 / 3600
Evaluate 70000 / 3600 = 19.444444444444
n₁ * 19.444444444444
Evaluate n₁ * 19.444444444444 = 700
700
The answer to the problem and the result of n₁ * (n₀ * 1000) / 3600 is 700
