#### 2.7.46 Types Tutorial Exercise 14

How long will it take for a signal to get from one end of the computer to the other?

    1:  m / c         1:  3.3356 ns
        .                 .

     ' 1 m / c RET        u c ns RET

(Recall, ‘`c`’ is a “unit” corresponding to the speed of light.)

    1:  3.3356 ns     1:  0.81356
    2:  4.1 ns            .
        .

      ' 4.1 ns RET        /

Thus a signal could take up to 81 percent of a clock cycle just to go from one place to another inside the computer, assuming the signal could actually attain the full speed of light. Pretty tight!
