Lucy is listening to her favorite album while jumping rope. She can jump the rope 1 time per second. If the album's songs are all 3.5 minutes long and there are 10 songs, how many times will she jump rope? Give me reasons, before answering the question
She can jump her rope 60 times a minute because 60 x 1 = 60. The album is 35 minutes long because 10 x 3.5 = 35. She will jump her rope 2100 times during the album because 35 x 60 = 2100. So the final answer is 2100.
