Ayush8750: don't answer stupido

Answered by Aadhi2001

Let AB be the height of the tip of the fishing rod from the water surface. Let BC be the horizontal distance of the fly from the tip of the fishing rod. Then AC is the length of the string. By Pythagoras theorm: AC^2 =AB^2 + BC^2 AB^2 = (1.8m)^2 + (2.4m)^2 AB^2 = (3.24 + 5.76)m^2 AB^2 = 9m^2 AB = square root of 9 AB = 3 m

Aadhi2001: Sorry half of the answer I forgot to answer.

Aadhi2001: Half of the answer I'm posting here

Aadhi2001: Thus the length of the string out is 3m.

Aadhi2001: She pulls the string at the rate of 5cm per second

Aadhi2001: String pulled in 12 seconds = 12 × 5 = 60 cm = 0.6m
