A cat and dog stumble across a sleeping skunk. They run away from it in opposite directions - the dog at a speed of 6 feet per second and the cat at a speed of 9 feet per second. How long will it be until the pets are 165 yards apart?

Speed = Distance/Time

Cat's Speed 9ft/s

Dog's Speed 6ft/s

Let x be the distance travelled by the Cat,

the distance travelled by te dog = 165 - x,

and t, the time spend

Cat's Speed 9ft/s = x/t

Dog's Speed 6ft/s = (165 - x) / t

Solving for t you will get t = 11 seconds
