Salt water has greater density than fresh water. a boat floats in both fresh water and in salt water. where is the buoyant force greater on the boat? salt water has greater density than fresh water. a boat floats in both fresh water and in salt water. where is the buoyant force greater on the boat? salt water fresh water buoyant force is the same in both. cannot be determined from the information given.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
