b) 900 light seconds
c) 9 light minutes
d) 9 ly
e) [tex]9 \times 10^5[/tex] km
f) [tex]9 \times 10^7[/tex] km
g) 9000 km

Answer :

Final answer:

The distance to Venus is 9 × 107 km.

Explanation:

The speed of light is 3.0 × 105 km/sec and it takes light 300 seconds to travel from Venus to Earth. To calculate the distance to Venus, we need to use the equation:

distance = speed × time

Substituting the given values, we get:

distance = 3.0 × 105 km/sec × 300 sec = 9 × 107 km

Therefore, the distance to Venus is 9 × 107 km. So, the correct option is f) 9 × 107 km.
