Every day, about 1 4 0 , 0 0 0 , 0 0 0 140,000,000140, comma, 000, comma, 000 plastic water bottles are bought in the United Sta
tes. Each bottle is about 0 . 2 5 0.250, point, 25 meters long, and the equator of the Earth is about 4 0 , 0 0 0 , 0 0 0 40,000,00040, comma, 000, comma, 000 meters around. How many times can the Earth's equator be circled by a line of plastic bottles used in the United States every day?
The length of plastic water bottles are bought in the United States every day = (the no. of plastic water bottles are bought every day)(length of each bottle) = (140.0 million bottle)(0.25 m) = 35.0 million meter.
The length of the equator of the earth = 40.0 million meter.
∴ The times can the Earth's equator be circled by a line of plastic bottles used in the United States every day = (The length of plastic water bottles are bought in the United States every day)/(The length of the equator of the earth) = (35.0 million meter)/(40.0 million meter) = 0.875 times.
