Question

If we decrease the time it takes for a car to travel over the same distance, this will

increase the speed.

have no effect on velocity or speed.

decrease the speed.

decrease the velocity.

Answer 1

Hi! We're looking at speed or velocity, distance, and time! If we're just talking about velocity, there's a relation between them that is very simple when written in math.

Do you know the equation for velocity? That's a great place to start.

Answer 2

decrease in speed

Answer 3

Why do you think that?

Answer 4

\(v=\dfrac{d}{t}\)

Answer 5

ok now what

Answer 6

idk what happens next im not good at science

Answer 7

Well, it says the distance \(d\) is the same, and \(t\) decreases.
\(v=\dfrac{d}{t}\)
\(\dfrac{d}{\Tiny t}=\)
Now the denominator is smaller than it was. The numerator is bigger in comparison. So, how will the velocity change?

The other way to think is that you're running on a track. You go around once. Then you go around again in a shorter time. Was your velocity faster or slower on that second lap?
