The speed of light to five sig fig is 2.9979*108 m/s. What is the (a) speed of light to three sig figs, (b) distance the light will travel in 30.5 seconds, (c) in 10 seconds, (d)

 

(a) The speed of light to three significant figures is: 3.00 x 10^8 m/s

 

(b) Light will travel: 3.00 x 10^8 x 30.5 seconds = 9.15 x 10^9 meters=9.15 x 10^6 km.

 

(c) Light will travel: 3.00 x 10^8 x 10 seconds     = 3.00 x 10^9 meters = 3.00 x 10^6 km.
