It will take Jon 240 minutes or 4 hours.
A²+B²=C²
6²+8²=C²
C²=100
C=10
Therefore the length of AB is 10 units
Remember the properties of logarithms. If you have ln81, you can pull out the power of two (9^2) and have 2ln9. Also, you could do ln9 + ln9 because 9*9=81 and ln9*9 = ln9 + ln9
With these properties, you can get 3lnx+2lny, which is 3u+2v according to the answer.
