Question

Speeds of a boat along the current and against the current are 16 km/hr and 12 km/hr respectively. What is the speed (in km/hr) of the current?

Answer 1

Answer:

2 km/hr

Explanation:

speed of boat = b

speed of current = c

Speeds of  boat along the current = b + c

Speeds of a boat against the current = b - c

b + c = 16

b - c = 12

2c = 4

c = 2 km/hr
