Answer:
13.75 m/sec
Step-by-step explanation:
Since the 'per second' part stays the same, simply multiply 22 kilometers by the reciprocal of 1.6:
[tex]22(\frac{1}{1.6})[/tex]
then simplify the fraction:
[tex]= 22(\frac{10}{16})[/tex]
[tex]= 22(\frac{5}{8})[/tex]
and solve to get
[tex]= 13 \frac{3}{4}[/tex] miles per second as the answer.
or optionally:
13.75 m/sec
