(a) Explanation The rated of 2017 Toyota Prius vehicle by EPA for city and highway driving are 54 mi/gal and 50 mi/gal. Then, the unit fractions for city driving are 1 gal 54 mi and 54 mi 1 gal and for highway driving are 1 gal 50 mi and 50 mi 1 gal . Note that, the unity fractions that cancels miles and replace it with gallons are 1 gal 54 mi and 1 gal 50 mi . Multiply by the fractions to convert miles to gallons for 300 miles city driving of Toyota Prius as follows. 300 mi = 300 mi × 1 gal 54 mi = 300 mi × 1 gal 54 mi = 300 × 1 54 gal ≈ 5.56 gal Hence, the gas consumed in gallon for 300 miles city driving of Toyota Prius is 5.56 gal. Multiply by the fractions to convert miles to gallons for 100 miles highway driving of Toyota Prius as follows. 100 mi = 100 mi × 1 gal 50 mi = 100 mi × 1 gal 50 mi = 100 × 1 50 gal ≈ 2 gal Hence, the gas consumed in gallon for 100 miles highway driving of Toyota Prius is 2 gal. Then, the total consume of gallon of gas for city and highway driving of Toyota Prius is 5.56 gal + 2 gal = 7.6 gal ( nearst tenth ) . The rated of 2017 Toyota Yaris vehicle by EPA for city and highway driving are 30 mi/gal and 36 mi/gal. Then, its unit fraction for city driving are 1 gal 30 mi and 30 mi 1 gal and for highway driving are 1 gal 36 mi and 36 mi 1 gal (b) To determine The total consume of gallons of gas for the Toyota Prius and Toyota Yaris in 100 mi of city and 300 mi of highway driving.

Question 3 (5pt): A chemical reaction. In an elementary chemical reaction, single molecules of two reactants A and B form a molecule of the product C : ABC. The law of mass action states that the rate of reaction is proportional to the product of the concentrations of A and B: d[C] dt = k[A][B] (where k is a constant positive number). Thus, if the initial concentrations are [A] = = a moles/L and [B] = b moles/L we write x = [C], then we have (E): dx dt = k(ax)(b-x) 1 (a) Write the differential equation (E) with separate variables, i.e. of the form f(x)dx = g(t)dt.
