Question 1112355
 The sides of a rectangle field are 50 and 120 feet. How many seconds are saved if a man walking at the rate of 4 feet per second takes the diagonal shortcut across the field instead of walking along the two sides? 
-----
(50+120)/4 - [sqrt(50^2+120^2)/4] = time saved
-----
42.5 - 32.5 = 10 seconds
