Two helicopters, H1 and H2, are traveling together. At time t = 0 hours, they separateand follow different straight line paths given byH1 : x = 6 + 40t, y = −3 + 10t, z = −3 + 2tH2 : x = 6 + 110t, y = −3 + 4t, z = −3 + tall coordinates measured in miles. Due to system malfunctions, H2 stops its flight at(446, 13, 1) and, in a negligible amount of time, lands at (446, 13, 0). Two hours later,H1 is advised of this fact and heads toward H2 at 150 mph. How long will it take H1to reach H2?
