# How many nanoseconds (1 nanosecond = 10^-9) does it take a computer signal to travel 60 cm at a rate of 2.4 * 10^10 cm/s?

$2.5 \text{ns}$

#### Explanation:

The time taken = distance/speed so:

$t = \frac{60}{2.4 \times {10}^{10}} = 25 \times {10}^{- 10} \text{s}$

$\therefore t = 2.5 \times {10}^{- 9} \text{s}$

$\therefore t = 2.5 \text{ns}$
