Light travels at a speed of 3.00 x 10^11 cm/s. What is the speed of light in kilometers/hour?

rewona [7]

As 1 km = 1000 m = 1000,00 cm,

So, 1 cm = (1/1000,00) km

1 hour = 60 × 60 s = 3600 s

So, 1 s = (1 / 3600) hour

The light travels at a speed of $3.00 \times 10^{11} \ cm/s$ .

In kilometer/hour,

$3.00 \times 10^{11} \ cm/s = 3.00 \times 10^{11} \frac{(1/1000,00) km}{ (1 / 3600) hour} = 108 \times 10^8 \ km/hour$
