Question

A turtle starts swimming from a point A located on the circumference of a circular
pond. After swimming for 4 meters in a straight line it hits point B on the
circumference of the pond. From there it changes direction and swims for 3 meters
in a straight line and arrives at point D diametrically opposite to point A. How far
is point D from A?

Answer 1

Answer:

Thales theorem states that any diameter of a circle  Subtends a right angle to any point on the circle.

So by applying Pythagoras's theorem  , We get the required distance=$5$
