A train 500 m long can cross an electric pole in 20 sec and then find the speed of the train?

A train 500 m long can cross an electric pole in 20 sec and then find the speed of the train?

Answer/Solution

90 Kmph

Steps/Work

Length = Speed * time
Speed = L/T
S = 500/20
S = 25 M/Sec
Speed= 25*18/5 (To convert M/Sec in to Kmph multiply by 18/5)
Speed = 90 Kmph

A train m long can cross an electric pole in sec and then find the speed of the train?

Calculated Answer

90

Step by Step Solution

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

n₀ =	500
n₁ =	20

(n₀ / 1000) / (n₁ / 3600)
Evaluate n₀ / 1000 = 0.5
0.5 / (n₁ / 3600)
Evaluate n₁ / 3600 = 0.0055555555555556
0.5 / 0.0055555555555556
Evaluate 0.5 / 0.0055555555555556 = 90
90
The answer to the problem and the result of (n₀ / 1000) / (n₁ / 3600) is 90
