Answer:
7) Mean = 48               8)  Mean = 59.6          9)  Mean = 31.6     10)  Mean = 42.1
    Median = 47.5              Median = 61                Median = 32           Median = 40
    Mode = 72                    Mode = 90                  Mode = 46             Mode = 51
    Range = 66                  Range = 79                 Range = 34            Range = 51

Step-by-step explanation:
It is given that, a mouse covered a distance of 3/24 miles over a distance of 3 hours. Each hour, the mouse traveled the same distance. Distance traveled in 1 hour can be calculated by dividing 3/24 miles by 3. So,

Matt calculations shows that the distance is 3/8 hours. While dividing 3/24 by 3, he doesn't take reciprocal of 3 as a result he get 9 on numerator and 24 on denominator. Simplified fraction of 9/24 is 3/8. But the correct answer should be 1/24 hours.
