The distances run are 4 km (Mama), 11 km (Mom), 5 km (Jay), 8 km (Sue).
Step2: Arrange in ascending order
4 km, 5 km, 8 km, 11 km.
Step3: Calculate the median
Since there are 4 values (an even - numbered data set), the median is the average of the two middle values. The two middle values are 5 km and 8 km. Median=$\frac{5 + 8}{2}=\frac{13}{2}=6.5$ km.
