HELLO DEAR,


GIVEN that:-

The speed of peacock and snake are same

Let the distance covered by them is x


PQ = 9m
PS = Xm
QS = (27 - x)

NOW,

IN ∆ PQS

PS² = PQ² + QS²


=> X² = 9² + (27 - x)²

=> X² = 81 + 729 + 54x + x²

=> X² - x² - 54x - 810 = 0

=> 54x = 810

=> X = 810/54

=> X = 15m

QS = (27 –x) m = (27 – 15) m = 12 m

Hence, the snake is caught at a distance of 12 m from the hole


I HOPE ITS HELP YOU DEAR,
THANKS

heya..!!!

let the distance the snake travels before being caught be x

Height = 9 m = PQ

PS = X

QS = (27 - X)

now IN∆PQS

Using Pythagoras

81 + (27 - x)²= x²

54x = 81 + 27²

x = 15

HENCE, the distance from the hole is 27 - 15 = 12m
