Best ResponseYou've already chosen the best response.1ah, whoops, I think I made a small mistake w/ the numbers > > should be x/120 + x/80 = 1 (since Tisha builds the box in 80 minutes, not 120)

Best ResponseYou've already chosen the best response.1well, we can still multiply to get rid of the fraction x/120 + x/80 = 1 let's multiply by 240 instead of 120 2x + 3x = 240 5x = 240 x = 48 min
