Beef Stroganoff

Beef Stroganoff, well-known underworld figure, is driving ten miles to rendezvous with his associates, Clams Marinara and Froglegs Sautee. It will be necessary for Beef to average 40 mph for the 10 miles in order to make the rendezvous on time. The first 5 miles are in town, and Beef averages 20 mph for those 5 miles. For the second 5 miles, which are in open country, how fast is Beef going to have to drive in order to get there on time? If he is late, his associates will divide up the loot without him.

Show/Hide Solution

Poor Beef: To average 40 mph for ten miles means he has only 15 minutes to make it to the rendezvous. But alas, in going the 5 miles through the city at 20 mph, he used up all 15 minutes. He cannot make the rendezvous on time no matter how fast he goes. Even the speed of light won’t quite do.
