Speed is the rate of change in _____.
A.velocity
B.time
C.direction
D.distance
I think it is D...?
You are correct.
distance/ time = speed.
Velocity is speed plus direction.
Thank you
You are welcome.
You are correct, speed is the rate of change in distance. To understand why, let's break it down:
Speed measures how fast an object is moving, and it is calculated by dividing the distance traveled by the time it takes to travel that distance. In other words, speed is the amount of distance covered per unit of time.
Now, let's consider the other options:
A. Velocity: Velocity is similar to speed, but it also takes into account the direction of motion. It is a vector quantity that includes both speed and direction.
B. Time: Time is not the rate of change itself but rather one of the factors used to calculate speed. Speed requires knowing both the distance traveled and the time taken.
C. Direction: Direction alone doesn't give us the rate of change. It is just the path or route taken by an object.
D. Distance: Distance is exactly what speed measures. It represents the total length traveled by an object.
In conclusion, speed measures the rate of change in distance, making option D, distance, the correct answer.
