Two balls are thrown upward from the edge of a cliff that is 432 ft above the ground. The first is thrown with an initial speed of 48 ft/s, and the other is thrown a second later with a speed of 24 ft/s. Let $t$ be the number of seconds passed after the first ball is thrown. Determine the value of $t$ at which the balls pass, if at all. If the balls do not pass each other, type "never" (in lower-case letters) as your answer.

Note: Acceleration due to gravity is $-32 ft/sec^2.$ $t =$
