Re: MrRubix's Riddle Thread
Here's my math Rubix.
Pretty much I did this a different way:
I decided how long would it take for the Emerald and Tass to go together to leave Fractal behind 18 miles. That would take 9 hours (27 miles fractal, 45 miles emerald/tass). That would give Tass 1 hour to go back to get fractalon the bike. Fractal would go another 3 miles per hour, and emerald would start walking 3 mph.
After 10 total hours, Tass and fractal would meet up at 30 miles, while emerald would be way up at 48 miles. After 9 more hours (and fractal on bike while tass walks besides him), Tass and fractal would finally catch up to emerald at 75 miles. A total of 19 hours.
Using the 75 miles, I'll compare it to 30 miles.
So 30/75=.4, or 40% of the way.
Therefore, 19*.4=7.6.
The answer I have is 7.6 hours, or 7 hours 36 minutes.
Edit: I'm pretty sure Rubix wanted this in our answer since it's part of the riddle's questions.
