15 m/s can be written in km/h as ______

A. 54

B. 44

C. 45

D. 56

The question was posed to me in unit test.

This intriguing question comes from Kinematic Equations for Uniformly Accelerated Motion topic in division Motion in a Straight Line of Physics – Class 11

The correct choice is A. 54

For explanation I would say: The formula for conversion is, km/h = (18/5) x m/s. Therefore, 15 m/s = 15 x (18/5) = 54 km/h.
