Consider the question. It took an alligator named Paul 4 hours to walk from his home at the River Nile to the Nile Delta. On the return journey, Paul traveled with six other alligators, the journey taking 2 more hours than Paul took to walk to the Nile Delta, to reach their home at the River Nile. What's the combined time the alligators walked?
 If the answer is '46'; explain the reasoning:
If on the return journey to its home, the alligator took 2 more hours than it took to travel to the Nile Delta, Paul took 4 + 2 = 6 hours to travel back to its home. The total time Paul took to travel from its home to the Nile Delta and back is 6 + 4 = 10. On his return journey, Paul traveled with six other alligators, and since each alligator traveled for six hours up the Nile to their home, they took a total of 6 * 6 = 36 hours to do so. Together with Paul, all the alligators took 10 + 36 = 46 hours traveling between Nile Delta and up the Nile.
