In a large urban area with a regular grid of east-west andnorth-south streets, an ambulance is responsible for allemergency calls in a square region that we shall label[-1,1] x [-1,1]. now the ambulance is located at theorigin (0,0). note that the travel distance to any of the4 corners is not sqrt(2), but 2. why?

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).
