Question 71

Speed of a speedboat when moving in the direction perpendicular to the direction of the current is 16 km/hr. Speed of the current is 3 km per hour. So the speed of the boat against the current will be (in km/hr)

Solution

Given, speed of the boat when moving perpendicular to the direction of current = 16 km/hr and speed of current = 3 km/hr

Speed of the boat in still water = 16 - 3 = 13 km/hr

Speed of the boat against current = 13 - 3 = 10 km/hr

Hence, option C is the correct answer.
