Question
Two helicopters, H1 and H2, are traveling together. At the time t 0, they separate
and follow different straight line paths given by
H1:
x = 6+ 40t
y = -3+ 10t
z = -3+2t
H2:
x 6+ 110t
y = -3+ 4t
z = -3+t
Time t is measured in hours and all coordinates are measured in miles. Due to an error,
H2 stops its flight at (446, 13, 1) and lands at (446, 13, 0). Two hours later, H is
informed about H2 and moved toward H2 at 175 mph. How long will it takes Hi to reach
H2?
