Which is faster: a speedboat on water traveling at 70 meters per second, or a supercar on the highway traveling 170 miles per hour. Use dimensional analysis to convert one type of speed to the other,and use only the facts in the green box above.

Consider the image attached of the map of UW campus. At noon, Alex exits Smith Hall at point A and starts walking at a constant speed directly towards the Art building (point B), hoping for a cup of coffee at Parnassus. She gets to point B after 60 seconds. at the same time (noon), Matt is at point C (near the Music building), walking straight towards point D at a uniform speed of 2 feet per second, rushing to his next class. Point B is 60 feet east and 110 feet north of point A. Point D is 80 feet due north of point A, and point C is 70 feet due east of point D. Determine parametric equations for Alex's and Matt's coordinates t seconds past noon.
