동대수석합격생요새 이런문제들이 자주 올라오길래, 한번 내볼려구요^^; 이번껀 쉽습니다. 한번 해보세여~
Juan and José are expert house painters. Once, they each timed how long it took the other to paint a tool shed. Juan completed his shed in 3 hours, 20 minutes. José, on the other hand, took an extra 25 minutes to paint an identical shed.
There is one more shed to paint today, identical to the other two they timed themselves on. They've decided to work together on this one. How long will it take if Juan and José work at the same rates that they painted earlier? [Express your answer in hours and minutes, with the minutes rounded to the nearest whole number.]
