Answer» Answer: 0.6 SECOND since time is inversely PROPORTIONAL to speed t1/t2 = speed1 / speed 2 Explanation: we know distance = speed x time = 330 x 3 = 990m in water speed becomes 1650 but distance is same time = distance / speed time = 990 / 1650 = 99 / 165 time = 33 / 55 = 3/5sec or 0.6 second |
