You are a member of your high school track team and you specialize as a long-distance runner. Your event is the 1500-meter run, also known as the metric mile, which you run at a constant rate. During one particular 1500-meter race you are 1200 meters from the finish line after running for 1 minute and 600 meters from the finish line after running for 3 minutes. What is your total time in minutes to complete this 1500-meter race and reach the finish line?

  • math -

    r = d/t = (1500-1200)/1min = 300 m/min =
    Rate of speed.

    T = 1500m * 1min/300m = 5 Min.
