Answer:

Step-by-step explanation:

The downstream speed is ...

speed = distance / time

speed = 36 km/(3 h) = 12 km/h

The upstream speed is ...

12 km/(3 h) = 4 km/h

__

If b and c represent the speeds of the boat and current, respectively, then we have ...

b + c = 12

b - c = 4

Adding these gives ...

2b = 16

b = 8

c = b -4 = 4

The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.
