Question

A train, 140 m long, passes a signal pole in 10 seconds. Find the speed of the train in
m/s and km/h
​

Answer 1

Answer:

• The speed of train in m/s and km/h is 14 m/s & 3.9 km/h respectively.

Step-by-step explanation:

Given that,

• Distance (D) = 140m
• Time (T) = 10s

As we know that,

✒ Speed (S) = Distance (D) / Time (T)

[ Putting values ]

➡ S = 140/10

➡ S = 14m/s

Now, m/s convert into km/h ; so,

✒ S = 14 × 5/18

➡ S = 0.78 × 5

➡ S = 3.9km/h

Hence Solved!!
