# Some Mathematical Meandering III

/In our last mathematical digression we studied the Snowplow Problem of Ralph Palmer Agnew, the solution of which using the logarithmic function appears on page 39 of his book *Differential Equations *(McGraw-Hill 1960). Let us make the problem even more interesting following a suggestion by Murray S Klamkin that is given in Bender and Orszag's *Advanced Mathematical Methods for Scientists and Engineers*. Here is the Great Snowplow Chase.

**One day it started snowing at a heavy and steady rate. Three identical snowplows started out at noon, 1 pm and 2 pm from the same place and all collided at the same time. What time did it start snowing?**
