Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
so
The distance is equal to multiply the speed by the time
Let
s ----> the speed in units per second
d ---> the distance in units
t ---> is the time in seconds
BUG A
we have
The speed is equal to
substitute
If x is the point reached by A after t seconds
then
Multiply the speed by the time
BUG B
we have
The speed is equal to
substitute
If y is the point reached by B after t seconds
then
Multiply the speed by the time
----> is negative because B is moving in the negative direction
