Today, my father and I went to Youfang Bridge by subway, from which I learned a truth.
We came to the subway first and found that there were 19 stations in the subway. Each stop is 2 minutes, and the stop time is 1 minute and 30 seconds. At this time, my father gave me a difficult problem: How many minutes does it take from Jing Tian Road to Youfang Bridge? I thought for a moment: "19 minus 1 equal to 18, 18 times 2 equals 36, 18 times 1 minute 30 seconds equals 1 hour1hour.
1 hour 12 minutes plus 36 minutes equals 1 hour 48 minutes. "Dad smiled and said," your algorithm is not simple. First subtract 19 from 1 equal to 18, so that you know a * * * with 18 parking times, plus 1 30 seconds equals 3 minutes and 30 seconds, and then multiply it by 3 minutes and 30 seconds. Do you think this method is simpler than yours? "
By taking the subway this time, I understand that although there are many math problems in life, some math problems are not simple, waiting for us to calculate them simply. In the future, I must study math seriously and solve more math problems.
