1.18 A gallon (3.8 liters) of gasoline that weighs 6.3 pounds (2.85 kg) can produce 20 pounds (9.1 kg) of carbon dioxide. Yes, 20 pounds (9.1 kg) of carbon dioxide!Assume 100 million people with cars (with 20 miles/gallon (10.6 km/liters) gasoline consumption rates) decide to walk 3 miles (4.8 km) a day (approximately an hour) instead of driving their cars. What would be the reduction in pounds of carbon dioxide released into the atmosphere on a yearly basis?Solution 100,000,000 people ×
