Answer 1

1 cow in 1 day can power 14 miles

1 cow in 365 days can power 14*365 miles = 5110 miles

Answer a: Number of cows needed to power 1,000,000 miles in 1 year = (1,000,000)/(5110) = 196 cows

1 car can travel 61 miles in 1 day at $11

For 1,000,000 miles cost = (1,000,000/61)*11 = $180,328

Answer b: Cost of driving 1,000,000 miles using gasoline = (1,000,000/33)*3.29 = $99,697

The second part will have the same result as $180328
