    "Rice and Wolman (1971) calculated that gray whales burn 19 kilocalories per kilogram of body weight per day. What's the conversion for tons to kilograms? How many kilocalories does a 40-ton whale burn per day?"

    To find my answer first I needed to know how many kilograms go into a ton. The answer to that is 1,000. Then I took 1,000 and multiplied it by 40 to get 40,000. Then since they burn 19 kilocalories a kilogram you take that number and muliply it by 19 to get the final answer witch is 760,000.
