Question

The speed of light is 3.0 × 105 km/sec, and it takes light 300 sec for light to travel from Venus to Earth. From this information, what is the distance to Venus?

a) 9 km
b) 900 light seconds
c) 9 light minutes
d) 9 ly
e) 9×105 km
f) 9×107 km
g) 9000 km

Answer 1

The distance to Venus is 9 × 107 km.

Step-by-step 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.
