You visit your grandma who has boxes of photo albums, important documents, and home videos (on HVS). there are a lot of family mebets in this media but everything is starting to fade and fall apart and you want to preserve it and make it accessible for the next generation. In addition, you want to be able go reliably and quickly send this memorabilia to your family members who live all over the world. you need to convince your grandma to convert all of her stuff to digital.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i. e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i. e. include the distance traveled to the first encounter)
