OK so the cone's volume is 12.57 however, the cup's volume is only 12.27. So, if they're both $2.50 then i would get the cone because it has more volume.
I think the answer is 384 in^3
169 miles * 5280 ft/ mile = 892320 ft
3 hours * 60 minutes/1 hr = 180 minutes
3 hrs 30 minutes = 180 minutes + 30 minutes = 210 minutes
169 miles/ 3 hrs 30 minutes = 892320 ft/ 210 minutes = 4249.1 ft/ minutes
Simplify it to 2x-4=8x-4
-6x=0
x=0
not sure if that counts as no solution or single solution though...
