Question
A stream flows at a rate of 3.9 km/hr. A boat has a speed of 7.6 km/hr. While in the stream the boat travels upstream a distance of 2 km as measured along the shore, then travels back downstream to its starting point. Neglect the time to turn around.
a. Find the time it takes the boat to go upstream
b. Find the time it takes the boat to do downstream
c. What would it have taken to make the entire round trip in still water?

Swims across Lake Erie are officially sanctioned by the Lake Erie Open Water Swimming Association. Your friend on the swim team wants to swim across the lake. The plan is that your friend will swim to Presque Isle starting at a location at Long Point, Ontario which is 24 miles due north of Presque Isle. You will be navigating a boat with a GPS. Your friend can maintain a speed of 1.80 mph in still water. All during the swim you observe that objects drifting in the water are moving at 0.70 mph to the east due to the current. a. What bearing should you maintain? That is what direction should you point the boat to reach Presque Isle? Give your answer relative to a compass direction (i.e., 30° north of west). Hint, you want your net velocity vector to be straight south. b. How long did it take your friend to swim across Lake Erie? c. What is the addition amount of time that your friend will need to swim compared to if there was no current (assume your friend swims at a constant rate)?arrow_forward

- 1) A man flies a small airplane from Fargo to Bismarck, North Dakota—a distance of 180 mi. Because he is flying into a head wind, the trip takes him 2 h. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 h 15 min. What is his speed in still air, and how fast is the wind blowing? a. what is the speed (mph) in still air? b. wind speed (mph)? 2)A boat on a river travels downstream between two points, 60 mi apart, in 1 h.
