what does it means when time is represented with a negative number in a situation about speed and direction
Answers
Step-by-step explanation:
We can use signed numbers to represent time relative to a chosen point in time. We can think of this as starting a stopwatch. ... A positive times a positive is positive. If a car is at position 0 and is moving in a negative direction, then for times after that (positive times), it will have a negative position.

Answer:
Time's gotten negative? No worries, It's in the past. :)
Step-by-step explanation:
Negative time shows the time that has passed before our experiment was being conducted.
For example:
A ball started moving in space at 10:00, at 10:30 you noticed it's movement and started digging out it'd trajectory.
According to you, the motion of the ball starts at 10:30, but actually, it started thirty minutes earlier.
So, If we plot a graph of velocity v/s time, with time along the x-axis, we'll represent 10:30 as x = 0(or t=0) and, thus, 10:30 will become -30.
______________________
Negative time just completes the trajectory of the particle we're interested in, and might help us solve problems based upon it's speed and direction (like finding it's acceleration or the cause of motion)

The attachment might help, tho the x and y axis are absent.
