SIGHTSEEING The distance you can see to the horizon is given by the formulad 1.5h , where d is the distance in miles and h is the height in feet above thehorizon line. Mt. Whitney is the highest point in the contiguous 48 states. Its elevationis 14,494 feet. The lowest elevation, at 282 feet, is located near Badwater, California.With a clear enough sky and no obstructions, could you see from the top of Mt. Whitneyto Badwater if the distance between them is 135 miles? Explain.Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc.22. SEISMIC WAVES A tsunami is a seismic wave caused by an earthquake on the oceanfloor. You can use the formula s 3.1d, where s is the speed in meters per second andd is the depth of the ocean in meters, to determine the speed of a tsunami. If anearthquake occurs at a depth of 200 meters, what is the speed of the tsunami generatedby the earthquake?Chapter 1 60 Glencoe Algebra 1
