please i have a problem that connects with (motion in one dimension),

can any one try and solved for me.

The problem is as follows:

a truck moves with a velocity 15m/s in the western direction of a collision path with a car that moves in the eastern direction with a velocity 30m/s and the distance between the two vehicles 400m.

1) calculate the collision time.[SIZE=7]

It looks like elementary arithmetic. The relative speed is 45 m/sec, so it takes 400/45 sec to collide.
