Question: Ashley is playing a game on her smartphone that measures the distance she walks. Every 2 kilometers, the game gives her a prize. Ashley starts the game and then walks 5 miles. How many prizes does she earn?
(Hint: There are 1.609 kilometers in 1 mile.)
Answer: 4 prizes
Solution: There are 1.609 kilometers to every mile. Ashley walks 1.609 kilometers, 5 times. That's 8.045 kilometers. Since she'll get a prize for every 2 kilometers she walks, she'll earn 8/2 = 4 prizes with 0.045 kilometers left over.
