Question

find speed if distance =400km and time = 100hr

Answer 1

Answer:

Speed is a scalar quantity that refers to "how fast an object is moving." ... An object with no movement at all has a zero speed. Just as distance and displacement have distinctly different meanings Speed and Velocity also have distinctly different meanings.

Speed is equal to the distance traveled divided by the time. If the Distance is in km and time is in hours then speed is measured in km/hr.

Speed = Distance/ Time

Speed = 400 / 4

Speed = 100 km/hr.
