    Answer:

    Part A

    0.764 minutes/miles

    Part B

    48.4 minutes

    Step-by-step explanation:

    a) Jasmine ran 55 miles in 42 minutes. Part A At what rate did Jasmine run?

    ​Jasmine ran at a rate of minutes per mile. ​

    Rate = Minutes/Miles

    Minutes = 42 minutes

    Miles = 55 miles

    Jasmine’s rate = 42 minutes/55 miles

    = 0.7636363636 minutes/miles

    Approximately = 0.764 minutes/miles

    Part B

    Katie ran 44 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer. ​ ​

    Rate = Minutes/Miles

    Minutes = ?

    Miles = 44 miles

    Rate = 1.1 minutes per miles

    Hence:

    1.1 minutes per miles = x/44 miles

    x = 1.1 minutes per miles × 44 miles

    x = 48.4 minutes
