SHORT TIME AND DISTANCE
A
procedure
called
“short
time
and
distance”
is
used
on
the
computer
to
solve
problems
involving
short
dis-
tances,
such
as
;
In
these
problems,
a
very
“smail
amount
of
time
is
involved
in
checking
speed.
For
the
short
time
and
distance
procedure,
“36”
re;
the
speed
index.
This
"36"
is
equal
to
3600
seconds
in
one
hour.
Figure
9
shows
the
“36”
position
on
the
rotating
“B”
scale
of
the
computer,
When
using
the
short
time
and
distance
procedure,
all
minutes
on
the
“B”
scale
represent
seconds.
For
example,
figure
9
shows
that
at
101
m.p.h..
40
sec-
Onds
are
required
to
travel
1.12
miles.
Similarly,
the
“C"
scale
is
changed
from
hours
to
minutes.
Figure
9
shows
that
at
101
mph.,
it
will
take
5
minutes
to
fly
8.4
miles.
