Relationship between speed, distance, and time

[cvc121]

Hi,

I am having trouble understanding the relationship between speed, distance and time. For example, if time was tripled, what would be the effect on distance? What about the effect on speed? Would they both increase 3 times as well?

Thanks! All help is very much appreciated!

All these answers will depend on the type of motion. More specific, you need to know how the acceleration changes with time.
As a trivial example if the object is at rest, nothing happens when you "triple the time", the velocity is still zero.

If you are driving at 20 mph for one hour, and then drive for two more hours, does that mean you are going faster?

The relation is just that. It is a relation among three variables. If you know what happens to two of them, you can find the third. If you just change one of them, then anything can happen to the other two. So a meaningful version of your question would be: If time were tripled, what speed would be needed to cover the same distance?, or, if time were tripled, and the speed remained the same, what would happen to the distance?
