Answer:

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

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

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

Answer:252 miles
Explanation:
Given
During his way to mountain it took 7 hr to drive
and during his return trip it took 4 hr to return
Let x be the distance between home and mountain
average speed for return is 27 miles per hour faster than his former trip
let v be the speed on his way to mountain thus v+27 is his return speed
thus
----1
for return trip
-----2
divide 1 & 2




thus
