So you know if a and b are the numbers that a+b=36 and a-b=4 so you can solve one I solved the second equation for a a=4+b and plugging that a value into equations gives you 4+b+b=36
This simplified to 4+2b=36
2b=32
B=16 so you know one number is 16 and you can plug it in to find a a-16=4 so a=20
Therefore the two numbers are 16 and 20

5% of 25 km is:
0.05*25 = 1.25 km
25 - 1.25 = 23.75
25 + 1.25 = 26.25
The possible range is (23.75, 26.25). Hope it helps
