- A body is dropped freely from the roof of a building, traveling in the middle of the last second of its fall.How long does it take to fall?A motorboat maintained a constant speed of 13 miles per hour relative to the water in going 22 miles upstream and then returning. The total time for the trip was 6.5 hours. Use this information to find the speed of the current.A river that is one-quarter of a mile wide is flowing at a speed of 1 mile per hour. A swimmer enters the river and swims directly toward the opposite bank at a speed of 6 miles per hour. The current alters the swimmer's direction and causes her to reach the opposite bank some distance downstream. Find the angle the swimmer's resultant path makes with the line directly across the river. (Use decimal notation. Give your answer to two decimal places. Include the degree sign in your answer.) angle How far downstream does the swimmer make landfall? (Give an exact answer. Use symbolic notation and fractions where needed.) distance = miles
