Q: The correct relation of speed, distance and time is ........
  • A. S = T/D
  • B. S = D/T
  • C. S = D x T
  • D. S = D – T
Correct Answer: Option B - Speed - The distance travelled by an object per unit time is called speed. i.e., Speed (S) = Distance (D )/Time (T) It is a scalar quantity. Its S.I. unit is meter / second.
B. Speed - The distance travelled by an object per unit time is called speed. i.e., Speed (S) = Distance (D )/Time (T) It is a scalar quantity. Its S.I. unit is meter / second.
