Answer:
17 m
Step-by-step explanation:
As shown in the figure, is the ground level,
is the old level of water which was at 20 m below ground level,
is the new level of water which is 5m above of old level. The height of wall of the well, 1.20 m, and the the pelly at 80 cm =0.80 m, has been shown too.
The minimum length of the rope is equal to the distance between the pully and the new water level, indicated by the length in the figure.
So,
Hence, Raghu must use a rope having the minimum length 17 m to draw water from the well.
For this case we have by definition:
1 Pint is equal to 0.5 quart
We must indicate how many quarts there are in 120 pints.
Making a rule of three we have:
1 pint --------------------> 0.5 quart
120 pints -------------> x
Where the variable "x" represents the number of quarts equivalent to 120 pints.
Thus, 120 pints are equivalent to 60 quarts
