📊 Work and Time Calculation 📊
B’s work rate = 1/12 (work done per day)
Since A works twice as fast as B, A’s work rate is:
A’s work rate = 2 × B’s work rate
= 2 × (1/12)
= 1/6 (work done per day)
Combined work rate of A and B = A’s work rate + B’s work rate
= 1/6 + 1/12
= (2 + 1) / 12
= 3/12
= 1/4 (work done per day)
Time taken by A and B to complete the work = 1 / Combined work rate
= 1 / (1/4)
= 4 days
🎉 A and B can together finish the work in 4 days. 📊
