Assuming that you meant she drives 129 km everyday (her work hours are not stated) then the answer should be 3999km.
To find this, simply multiply her daily kilometers (129) by the days (31) in order to find how many she drives in the set period of time provided.
Hope this helps!

I’m not sure but i think 66 hours because both pumps must fill half of the pool which would split the timing for each which would make pump 1 take 36 hours to fill half and pump two take 30 hours to fill the rest. when you add these hours it equals 66. i hope i helped :)
