In this episode, Harriet and Clayton Quigg (mother and son stars of many word problems I have written over the years) meet to have a chat and take a walk. They rendezvous at the Welcome sign (N 38º 34.453’, W 121º 43.807’) of a local greenbelt, carefully note all the numbers and all the rules and proceed to a nearby bench to chat. Suddenly, Clayton jumps up and hurries off along the path in an easterly direction at 200 ft/min. Five minutes later, Harriet follows walking at 300 ft/min. At the point that she catches Clayton they notice a number near the path. They call this number A and make the following calculation:
B = (3A – 12)/1000.
They call the digit that appears most often on the Welcome sign, C, and make the following calculation:
D = C + 15C/1000.
To find the final cache they subtract B from the minutes of the rendezvous latitude and subtract D from the minutes of the rendezvous longitude and off they go to find the cache. They remembered to bring a pencil or pen and they hope you do, too.
