V teplokh = 21.6 km/h the V leak = 4.9 km/h of V in leaks - V against a leak - 21.6+4.9 = 26.5 km/h - speed on a current. 21.6-4.9 = 16.7 km/h - speed against the current. 1) 21.6+4.9=26.5km/h - motor ship speed on a current 2) 21.6-4.9=16.7km/h - motor ship speed against the current Answer: motor ship speed on a current is equal 26.5km/h, and the speed of the motor ship is against the current equal 16.7km/h.
