My question is: Keanu's motorcycle can store 8 liters of gasoline. If his destination is 280 miles away and his motorcycle consumes 8 liters of gasoline per 40 miles, how many times does Keanu have to refill his motorcycle with gasoline if he will make a round trip? Your thoughts:
The total number of miles for a round trip is 280 x 2 = 560. Therefore, he needs to refill his motorcycle 560 / 40 = 14 times. The final answer: 14.
