Kathy and Ali are re-painting their apartment. Kathy paints at $k$ square-feet every $10$ minutes, Ali paints at $a$ square-feet every $10$ minutes. Kathy takes a $5$ -minute break every hour, Ali takes a $10$ -minute break every $90$ minutes.

How much total wall space, $T$ , would Kathy and Ali have painted after $3$ hours? Represent this amount with a literal equation.
