Answer:
1. 15 days
2. 0.17 acre.
Explanation:
1. Determination of the number of days.
From the question given above,
The crew clears ⅓ acre of land in 2 days.
Therefore, the crew will clear 2½ acres in = (2½ × 2) / ⅓
= (5/2 × 2) × 3
= 15 days
Thus, the crew will clear 2½ acres in 15 days
2. Determination of the acre of land.
From the question given above,
The crew clears ⅓ acre of land in 2 days.
Therefore, the crew will clear X acre of land in 1 day i.e
X acre of land = ⅓ ÷ 2
X acre of land = ⅓ × ½
X acre of land = 1/6
X acre of land = 0.17 acre
Thus, the crew will clear 0.17 acre of land in 1 day
