Answer:

[tex]t=2.51min[/tex]

Explanation:

The time taken by the light to travel a given distance is defined as:

[tex]t=\frac{d}{c}[/tex]

Here c is obviously the speed of light. Now we convert the average distance form Venus to Earth to meters:

[tex]28*10^{6}mi*\frac{1609.34}{1mi}=4.51*10^{10}m[/tex]

Finally, we calculate the minutes taken by the light to travel from Venus to Earth:

[tex]t=\frac{4.51*10^{10}m}{3*10^8\frac{m}{s}}\\t=150.33s*\frac{1min}{60s}=2.51min[/tex]
