Particle P starts at the origin at

t=0

with a constant velocity of

4\text{ ft/s}

. Particle Q is located

30\text{ ft}

to the right of the origin but does not begin moving leftward with a constant velocity of

6\text{ ft/s}

until

t=2\text{ s}

. Determine the time, in seconds after

t=0

, when the particles pass each other.
