Question

The water level in a well is 25 m below ground level and the wall of the well is 2 m high. If ground level is represented as 0, represent the water level in the well and the top of the well as integers. Also find the minimum length of rope required to draw water from this well. The ground level is represented as 0. Since the water level in the well is 25 m below ground level, the water level can be represented as:

Answer 1

Answer:

Solution:

(a): Height of the wall of the well = 1 m 20 cm = 1.20 m

Height of the pulley = 80 cm = 0.80 m

∴ Required minimum length of the rope

= (20-5+ 1.20 +0.80) m

= (15 + 2) m = 17 m

Answer 2

Answer:

-25

Step-by-step explanation:

The answer is -25 as its 25 m in the ground like in ti so we will write it as -25.
