E
d. 115
2. the speed at any instant of time is known as
a. average speed
b. velocity
c. given speed
d. instantaneous speed

The speed given at any instant of time is called as the instantaneous speed.

Option D

Explanation:

The formula for the instantaneous speed takes up the nth time in consideration rather than taking up the total time. along with the instantaneous speed, same concept applies on instantaneous velocity and instantaneous acceleration.

The instantaneous speed depicts the speed at the given time. The motion which is being observed in a particular second or minute or hour is the instantaneous. For example, the nth second, gives the particular velocity or speed or acceleration.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
