<human>:  It takes John 5 minutes to get to the first side of the Rubik's cube. The second and third sides each take twice that long. The last 2 sides each take half as long as the first, and once you get the 5th side you have all 6 sides. How long does the Rubik's cube take?
<bot>: How long does the second and third sides take? ** The second and third side each take 2*5=<<2*5=10>>10 minutes
How long do the second and third sides take together? ** So they take 10*2=<<10*2=20>>20 minutes together
How long do the last 2 sides take? ** The last 2 sides take 5/2=<<5/2=2.5>>2.5 minutes
How long do the last 2 sides take together? ** So they take 2.5*2=<<2.5*2=5>>5 minutes
How long does the Rubik's cube take? ** So the total time is 5+20+5=<<5+20+5=30>>30 minutes
