What is the si unit of speed


S.I unit of speed is m/s ,                                   proof,                                                speed=, distance by , time,    (S.I unit of Distance is Meter it denotes by m and S.I unit of time is Second it denotes by s)  so, m by s or m/s                                                                                                                                       ,SI unit of speed is m per second or mps,m/s is the SI unit of speed,Metre/second or m/s or mps,Speed=m/s is right answer,Speed so unit is m/s as speed =distance÷time =m÷s so ,speed so unit is m/s
