How long will it take the same crew to clear the entire plot of 2 1/2 acres?

1. 15 days

2. 0.17 acre.

Step-by-step 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

the answer is 5/3x+7/5y+7
