A hummingbird needs 10 grams of sugar and 8 grams of protein each day. One honeysuckle flower provides 20 mg of sugar and 10 mg of protein. One nasturtium flower provides 10 mg of sugar and 10 mg of protein. It takes 10 seconds to feed from a nasturtium and 15 seconds per honeysuckle. How many minutes does it take to get exactly the food it needs? (Remember that 1 gram equals 1000 mg.)
