Answer:
B. 180 meter
Explanation:
Given,
Velocity of boat with respect to still water=2 mps
Velocity of water with respect to shore= 1 mps
Also the boat is moving in opposite direction to that of water
Hence,
velocity of boat with respect to shore=2-1=2 mps
Given time=3 minutes=180 seconds
Hence
Displacement of boat with respect to shore= velocity*time=180*1=180 meter
