A Problem In Many People’s Lives

I am a problem in many people’s lives. At times (even more than once) I’m useful. The older I grow, the less useful I become. Who am I?

Show the answer »

Credit or debt. Debt is a problem in many people’s lives, but in order to go to school or make a large purchase, it can be useful. As your debt grows older, it’s more unpleasant than useful.

Noah, Emma and the Ice Cream Truck

Noah and Emma, track stars with superb hearing, ran as fast as they could to catch up to the ice cream truck in the next town over. They averaged 6 miles per hour, then rested to enjoy their ice cream. They averaged 4 miles per hour over the same distance on the way back. Not counting the time they rested, what was their average speed?

Show the answer »

4.8 miles per hour. 5 mph is tempting, but incorrect. Pick any distance, say 12 miles there and 12 miles back. They take two hours to cover the first 12 miles and three hours to cover the return trip. In 5 hours they covered 24 miles which is an overall average of 4.8 miles per hour.
