A train moves at a speed of 108 km/hr. What is its speed in m/s?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 30
1 km \(=1000\) m and 1 hour \(=3600\) s, so 1 km/hr \(=\frac{1000}{3600}=\frac{5}{18}\) m/s.
\(\displaystyle 108\times\frac{5}{18}=6\times5=30\) m/s
The speed is 30 m/s.
