Write equations for the positions of A and B vs time t.
Set them equal and solve for t. Point B may spend some time going right and then, after reversing direction, additional time going left. If that happens, you will need to calculate when A reverses direction and add the right- and left-going distances.
Points A and B move along two adjacent
parallel paths. Initially A is 100 ft to the left of
B, and each point has a velocity of 5 fps to the
right. the velocity of A remains constant and the
acceleration of B is 2 fps2 to the left.
Determine the total distance traveled by B when
the two points pass each other.

soo if we look at A as the orgin. The equation for X(A) is 5t and the Equation for x(B)= -2t^2+5t-100??
B does spend time going to the right before changing direction
