1.In an experiment reported in the scientific literature, male cockroaches were made to run at different speeds on a miniature treadmill while their oxygen consumption was measured. In one hour the average cockroach running at 0.064 km/hr consumed0.71 mL of O₂per gram of insect weight (at 1.1 atm pressure and 23^oC).

How many grams of O₂would be consumed in 1 hour by a 5.5 g cockroach moving at this speed?

2.The Trans Alaskan Pipeline pumps enough crude oil every day to make about 5.3912 x 10⁵barrels of gasoline. If you own a car that gets 4.42 miles per liter, how many years can you drive at 1457 cm/s before 5.3912 x 10⁵barrels of gas is used up? (1 barrel = 42 gallons exactly)
