Company Z has 10 employees that can dig a well in 20 days. However, when Company Z started digging a new well, there were only 5 workers available for the first 8 days. After that, all 10 workers were available to work on the well until it was finished. How much longer did it take them to finish the well compared to if all 10 workers had been available from the start?

It's true — sand dunes in Colorado rival sand dunes of the Great Sahara Desert! The highest dunes at Great Sand Dunes National Monument can exceed the highest dunes in the Great Sahara, extending over 700 feet in height. However, like all sand dunes, they tend to move around in the wind. This can cause a bit of trouble for temporary structures located near the "escaping" dunes. Roads, parking lots, campgrounds, small buildings, trees, and other vegetation are destroyed when a sand dune moves in and takes over. Such dunes are called "escape dunes" in the sense that they move out of the main body of sand dunes and, by the force of nature (prevailing winds), take over whatever space they choose to occupy. In most cases, dune movement does not occur quickly. An escape dune can take years to relocate itself. Just how fast does an escape dune move? Let x be a random variable representing movement (in feet per year) of such sand dunes (measured from the crest of the dune). Let us assume that…

Two classmates have decided to read all the volumes in a popular series of books. Mia has already read 12 volumes and will continue to read new ones at a rate of 1 volume per week. Beth, who hasn't started reading the series yet, will read 4 volumes per week. At some point, Beth will catch up with Mia and they will be reading the same book. How long will that take? How many volumes will each girl have read by then? In ? weeks, the girls will each have read ? volumes in the series.
Two persons are to run a race, but one can run 9 meters per second, whereas the other can run 5 meters per second. If the slower runner has a 50-meter head start, how long will it before the faster runner catches the slower runner, if they begin at the same time?
