Solving Rate Problems: Boat Speed, Wind Speed, and TankFillingSection 6.8: Exercises 36, 54, 6436). Upstream downstream. Junior’s boat will go 15 miles per hour in still water. If hecan go 12 miles downstream in the same amount of time as it takes to go 9 milesupstream, hen what is the speed of the current?Speed of current = x mphSpeed when downstream = (15+x)mphSpeed when upstream = (15-x)mphspeedcedistimetanDistanceNow according to the question both time are same so143.271521454521135180129121809135)15(1215(91512159xxxxxxxxxxxxThe speed of the current will be 2.143 mph#54). Big Plane. A six passenger plane cruises at 180 mph in calm air. If the plane flies7 miles with the win in the same amount of time as it flies 5 miles against the wind, thenwhat is the wind speed?Speed of wind = x mphSpeed of plane in the direction of wind = (180 +x) mphSpeed against direction = (180-x) mph
