None of the above

Detailed explanation-1: -The speed of an object is found out by dividing the distance that the object covers by the time in which the object takes to cover this distance. If ‘D’ is the distance traveled in some time ‘T’ then the speed of the object for this journey or ‘s’ is equal to s = D/T.
Detailed explanation-2: -The general speed average formula for an object is given as [Average Speed = Total Distance Traveled ÷ Total Time Taken]. SI unit of average speed is m/s.
Detailed explanation-3: -time (v = d/t), or equivalently, that time = distance/speed (t = d/v).
Detailed explanation-4: -That is speed = distance ÷ time. Or to put it another way distance divided by speed will give you the time. Provided you know two of the inputs you can work out the third. For example if a car travels for 2 hours and covers 120 miles we can work out speed as 120 ÷ 2 = 60 miles per hour.
