How long will it take?
Two boys, Johnny and Tommy, splash water at each other, 1 trying to get even with the other. Then they use the hose, and still can't keep even. Now the 2 boys are chasing each other with squirt guns; Johnny running away from Tommy. If Johnny is going at 5 mph and Tommy is going at 8 mph, How many seconds will it take for Tommy to catch Johnny?
