Water is flowing from a major broken water main at the intersection of two streets. the resulting puddle of water is circular and the radius r of the puddle is given by the equation r = 6t feet, where t represents time in seconds elapsed since the the main broke. (a) when the main broke, a runner was located 5 miles from the intersection. the runner continues toward the intersection at the constant speed of 16 feet per second. when will the runner's feet get wet? 20 min (b) suppose, instead, that when the main broke, the runner was 5 miles east, and 5000 feet north of the intersection. the runner runs due west at 16 feet per second. when will the runner's feet get wet? (round your answer to one decimal place.) 21.4 min additional materials
