Answer 1

20 minutes is the answer

Answer 2

Let's consider AB to be h. Then,

BD=h/tan30∘=h√3

BC=h/tan60∘=h/√3

CD=BD−BC=2h/√3

If the speed of the boat is x metres per second,

CD=2h/3=600x⟹h/x underoot3=300

Time in which the boat travels distance BC is :

BCx=h/x underoot3=300 sec

Hence, the boat takes 300 seconds or 5 minutes to reach the shore. In total, it takes 15 minutes to cover distance BD.

Hope it will help u buddy
