A speed of \(54\ \text{km/h}\) is equal to:
A speed of \(54\ \text{km/h}\) is equal to:
Show Hint
To convert \(\text{km/h}\) into \(\text{m/s}\), multiply by \(\frac{5}{18}\). To convert \(\text{m/s}\) into \(\text{km/h}\), multiply by \(\frac{18}{5}\).

- \(10\ \text{m/s}\)
- \(12\ \text{m/s}\)
- \(15\ \text{m/s}\)
- \(20\ \text{m/s}\)

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
To convert speed from \(\text{km/h}\) to \(\text{m/s}\), multiply by: \(\displaystyle \frac{5}{18}\)
Step 1: Write the given speed.
\(\displaystyle 54\ \text{km/h}\)
Step 2: Convert into \(\text{m/s}\).
\(\displaystyle 54\ \text{km/h}=54\times \frac{5}{18}\ \text{m/s}\) \(\displaystyle =3\times 5\ \text{m/s}\) \(\displaystyle =15\ \text{m/s}\)
Step 3: Final conclusion.
Hence, \(\displaystyle \boxed{54\ \text{km/h}=15\ \text{m/s}}\)
