Q98 and 102
(8.7) Write an equation and solve. 97) A boat can travel 8 miles downstream in the same amount of time it can travel 6 miles upstream. If the speed of the boat in still water is 14 mph, what is the speed of the current? 98) The ratio of saturated fat to total fat in a Starbucks tall Caramel Frappuccino is 2 to 3. If there are 4 more grams of total fat in the drink than there are grams of saturated fat, how much total fat is in 2 Caramel Frappuccinos? (Starbucks brochure) Crayton and Flow must put together notebooks for each person attending a conference. Working alone, it would take Crayton 5 hours while it would take Flow 8 hours. How long would it take for them to assemble the notebooks together? 99) When the wind is blowing at 40 mph, a plane flying at a constant speed can travel 800 mi with the wind in the same amount of time it can fly 600 mi against the wind. Find the speed of the plane. 100) (8.8) Solve each problem by writing a variation equation. 101) Suppose c varies directly as m. If c -56 when m - 8, find c when m 3. 102) Suppose A varies jointly as t and r. If A 15 when andr 5, find A when t 3 andr 4. Suppose z varies inversely as the cube of w. If:- 16 when w 103) 2, find z when w 4. www.mhhe.com/messersmith
