Average **Speed** versus **Instantaneous Speed**. Since a moving **object** often changes its **speed** during its motion, it is common to distinguish between the average **speed** and the **instantaneous speed**. **Instantaneous Speed** – the **speed** at **any** given **instant** in **time**.

Regarding this, how do you find speed at a certain time?

Divide the distance by the **time** to **find** the **speed**. All you need are these two pieces of information to **find** your **speed** for the trip. The distance over the **time** will give you the object’s **speed**. In our example, 100 miles/2 hours = 50 miles/**hour** (about 80 kilometers/**hour**).

One may also ask, can the instantaneous velocity of an object at an instant? **Can the instantaneous velocity of an object at an instant** of time ever be greater in magnitude than the average **velocity** over a time interval containing the **instant**? At point of contact, the **velocity** is zero. At the point furthest from the road, the **velocity** is twice the **velocity** of the car.

Hereof, what is the formula for speed?

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by **time**. To solve for **time** use the formula for **time**, t = d/s which means **time** equals distance divided by speed.

How is the speed of a body related to its velocity?

The **velocity** of an object is defined as the change in displacement with the change in time. Since displacement is a vector quantity the **velocity** is also a vector with both magnitude and direction. The **speed** of an object is defined as the distance travelled Δs divided by the time period Δt taken to travel that distance.
