9. i hypersonic scramjet. on march 27, 2004, the
united states successfully tested the hypersonic
x-43a scramjet, which flew at mach 7 (seven
times the speed of sound) for 11 s. (a) at this rate,
how many minutes would it take such a scramjet
to carry passengers the approximately 5000 km
from san francisco to new york? (use the speed
of sound at 0° c, 331 m/s.) (b) how many kilo-
meters did the scramjet travel during its 11 s test?
