Standing on a one way street, were two highway patrol officers, specifically looking for drivers who were in violation of local traffic laws.
A taxi driver was going the wrong way down the street, however, the officers did nothing. What explanation can you offer?

Hint: Do taxi drivers always drive their taxi?
The taxi driver was walking at the time and not driving their cab, therefore breaking no traffic laws.

Many years ago, a cruise liner sank in the middle of the Atlantic Ocean. The survivors luckily landed on a remote desert island.
There was enough food for the 135 people to last four weeks.
Nine days later a rescue ship appeared, unluckily this ship also sank, leaving an additional 36 people stranded on the island to now share the original rationed food.
The food obviously had to be re-rationed, everyone was now on three-quarters of the original ration, so how many days in total would the food last, from the day of the original sinking?

Hint: How many rations did they start with?
Answer: 29 days.
Originally there was enough food for 135 people for 28 days, which totals 3780 rations.
After 9 days, 1215 rations had been eaten.
Therefore there were now 2565 rations left for 171 people, which would last for another 20 days at three-quarter rations per person = (2565 ÷ (3 ÷ 4)) / 171.
Which is 29 days in total from the original sinking.
