GENERAL KNOWLEDGE

Detailed explanation-1: -The meter per second (symbolized m/s or m/sec) is the Standard International ( SI ) unit of linear speed. This quantity can be defined in either of two senses: average or instantaneous.

Detailed explanation-2: -1 m/s is equivalent to: = 3.6 km/h (exactly) ≈ 3.2808 feet per second (approximately) ≈ 2.2369 miles per hour (approximately)

Detailed explanation-3: -The metre, symbol m, is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m s–1, where the second is defined in terms of the caesium frequency Cs. This definition implies the exact relation c = 299 792 458 m s–1.
