Question
If we denote speed by S, distance by D and time by T, the relationship between these quantities is ______.
Options
S = D × T
T = `"S"/"D"`
S = `1/"T" xx "D"`
S = `"T"/"D"`

Solution
If we denote speed by S, distance by D and time by T, the relationship between these quantities is `underlinebb(S = 1/T xx D)`.
Explanation:
Speed (S) is calculated as the distance (D) traveled divided by the time (T) taken to travel that distance.
Therefore, the correct formula is `S = D/T`
