ok Dude,
so first were gonna find out how many they can do in a second.
Robby here can do .6666666666667 in a minute
and Paul wall can do 1.33333333333333333 in a minute
so were gonna say that rob did 115 and paul did 230 (because paul can do double)
So if we multiplied the seconds we would get around 6 minutes and 5 seconds
so the answer is 7 minutes
YEAUHHHH
