Take the sun to be $1.5 \times 1 0^{11}$ m away. If a medium existed in which sound travelled at 340 m/s, how many years would the sound take to arrive?

Answer:

Solution:

$t = 1.5 \times 1 0^{11} /340 = 4.4 \times 1 0^{8}$ s, and dividing by $3.16 \times 1 0^{7}$ s per year gives about 14 years. Light takes about 500 s.
