Instantaneous speed is the velocity of an object at a certain time. For example:- Suppose you are driving in a car and the speedometer constantly varies; this is because the speedometer gives speed at a particular moment of time.
For example, where the current is swift, the bottom hard and smooth, and the car's body low to the ground, as little as one foot (30 cm) of water with a speed of 6 mph (10 km/hr) or 10 feet per second (3 m/sec) will move most cars.
