b) around 240 miles
c) around 630 miles

wait for it….

Answer: C. A gallon of gasoline contains about 31,000 calories, and “Bicycles can travel at least 10 times farther on a given amount of energy than the most efficient car,” according to Nicholas Goddard, a graduate of Duke University who decided to see just how far he could bike on 31,000 calories. He rode the 633 miles over eight days, eating a wide range of foods, including “two Gatorades, five ham-and-cheese sandwiches, a steak burrito from Cosmic Cantina, a glass of sangria, a quesadilla, chips and salsa, and a pint of beer.”
