Question

a train moving with a uniform speed of 54kmph what is its speed in m/s

Answer 1

54 km/h= 54*1000/3600=15 m/s

Answer 2

Answer:

= 15 m/s.

Step-by-step explanation:

Given:-

★ A train moving with a uniform speed of 54 kmph.

ㅤ

Find:-

★ What is the speed in minute/second.

ㅤ

Calculations:-

ㅤ

Note the terms:-

• km = kilometer.
• hr = hour.
• 1 km = 1000 m.
• 1 hr = 3600 sec.

ㅤ

If, 1km/hr = 1000/3600 (To convert this into m/s unit you have to divide 1km/1hr and simplify it).

ㅤ

Then, 54 km/hr = 54 × 5/18

= 5 × 3

= 15 m/s.

ㅤ

Therefore, 54 km/hr is equal to 15 m/s.
