There's simply not enough info here to facilitate a meaningful response.
Let's narrow things down a bit:
"Together they spent most of their waking hours engaged in programming tasks" could be written "<span>They spent approx. 24 hours total, over 3 weekends engaged in programming tasks, or roughly 72-100 hours, to come up with this "</span><span>"Ro-Bot-Ro-Call" game.</span>
There is little information please state more points.
<span>Nevermind the answer was x=1 and x=2. If anyone is wondering how to do it you can put the denominator in desmos and where the 2 points hit the x axis is your answer.</span>
