Do you enjoy wasting time and money, and polluting the environment? If not, then consider clustering your errands.
Take a look at this diagram:
Suppose you life at Point A. You have have four errands you need to run at Points B, C, D, and E. How many miles would you save by clustering your errands?
If you decided to do each errand separately:
A to B, and back to A = 10 miles
A to C, and back to A = 16.6 miles (Law of Cosines states c2 = a2 + b2 – 2ab cos C.)
A to D, and back to A = 16.6 miles (same as A to C, and back to A)
A to E, and back to A = 10 miles
Total = 50.2 miles
If you decide to cluster your errands:
A to B to C to D to E and back to A = 25 miles
Boom. Less than 50% of the mileage, gas consumption, time, carbon dioxide, etc. So, cluster your errands, or we will make you do more math.
If you answered “yes” to the first question, perhaps consider donating that time and money to a good cause.
