Conversions of minutes (and decimal minutes) to seconds, or vice versa, can be made by
using the small "SEC" arrow and the rate index (▲) which are located on the TIME scale,
see Figure 4.3-13. Place the rate index (inner scale) under the number of minutes on the
outer (white) scale and read the number of seconds opposite the "SEC" arrow on the same
Convert 3.7 minutes to seconds.
Place the rate index (on the inner scale) opposite 37 (which represents 3.7 minutes)
on the outer scale.
On the DISTANCE (outer) scale, opposite the "SEC" arrow on the TIME (inner)
scale, read the number of seconds (Figure 4.3-13).
222 seconds. Use the innermost scale on the time scale to convert to
minutes and seconds.
Look under 222 and read 3 minutes 42 seconds

CR-3 computer and are used in solving problems of time, distance, speed, and fuel
consumption/conversion. If any two of three components are known, the third component
can be easily computed. One problem in solving a ratio for the unknown factor is
determining the position of the decimal point. Since each value on the computer represents
a multiple of ten, a rough estimate should be made of the answer in order to interpret
