    1. A person starts running for an objective 12 kilometers away, at 12 kilometers per hour. 45 minutes later, someone starts running toward that objective, from the same start position, at 24 kilometers per hour. Who reaches the contest first?

    2. A person has $1000 which is yielding 6% interest per year over the time of the investment. He reinvests the interest he or she has gained. After 10 years, how much money does this person have?

    3. There is a small town, small supermarket. A bunch of burglars stole the money from it. How did they do it? What was their plan of action? Name a plan that might've worked.

    4. A person is riding on a train that averages precisely 150 kilometers per hour. It would normally take 2 hours to reach a destination. But it's average speed is 15% higher this time. How long does it now take to reach that destination?
