The days she has recorded: 11 + 10 + 7 + 6 + 3 + 2 = 39 The mode distance (most often): 5 km Median distance: 6.64 km ~= 6.5 km ~= 7 km by rounding upwards, so 3rd
When trying to find a percent, it is best to multiply everything by 100 (as a percentage is out of 100). 0.03*100= 3 and 1*100=100. Therefore, 0.03 as a percent is 3%
Hope this helps :)
