Fly Fishing Techniques

1.Canoe A needed 1.5 hours to travel from Duck Wharf to Bugler’s Bay. Its rate in still water was 12 km/hr, but it was going with the current. Canoe B was traveling at 14 km/hr in still water, but it was going from Bugler’s Bay to Duck Wharf, and the current was against it. Canoe B took five hours to make the trip. What was the rate of the current?

3.Two cars leave town at the same time traveling in opposite directions. One car travels at a rate of 60 miles per hour. The other car travels at a rate of 70 miles per hour. How far apart will the two cars be at the end of 4 hours?

5.Brad walks and jogs to school every day. He averages 5 km/hr walking and 9km/hr jogging. The distance from home to school is 6 km, and the total trip takes 1 hour. How far does Brad walk?

6.A plane climbs into the jet stream which is flowing at a rate of 80 miles per hour. Traveling with the jet stream for 5 hours, the plane covers 1,150 miles. The plane then reduces its altitude and flies out of the jet stream. Continuing for another 5 hours, the plane covers only 750 miles. How fast is the plane flying out of the jet stream?

9.A fisherman travels downstream at full speed to his favorite fishing spot. The stream is running at a rate of 5 miles per hour, and he takes an hour to get to the fishing hole. He catches 5 fish and calls it a day. He takes twice as long at full speed to get back to the dock going against the current. How fast will his fishing boat go?

10.A private airplane leaves an airport and flies due east at 192 km/hr. Two hours later, a jet leaves the same airport and flies due east at 960 km/hr. How long after the jet leaves will it overtake the plane?

11.An airplane flew for 4.23 hours with a 25.5-km/hr tail wind. The return flight against the same wind took 4.97 hours. Find the speed of the plane in still air.
