Answers
Explanation:
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour
.There is, in fact, a relationship between speed and time. S= d/t, where S is speed, d is distance, and t is time. So speed is dependent on time, as in the speed
is determined by the distance divided by the time
.An auto-rickshaw can move slow or fast depending upon the traffic, an auto-rickshaw can move faster than a bicycle but an aeroplane can move faster than the auto-rickshaw, how can we decide if one object is moving faster or slower than the other
