Rate of motion is measured by speed. It's SI unit is m/s and km/hr.

$\huge{\blue{\boxed{\boxed{\green{\underline{\red{\mathfrak{InFoRmAtIoN}}}}}}}}$

⭐$\bold{\pink{\underline{\orange{Speed}}}}$ ➡️ Speed is the distance talravelled by the object in unit time. Speed is a scalar quantity.

Speed = Distance travelled / Time

⭐$\bold{\pink{\underline{\orange{Scalar\: Quantities}}}}$ ➡️ The physical quantities which are specified with magnitude only are called scalar quantities.

Example :- Length, Speed, Mass, etc..
