The answer to your question is: Marc won't be on time for dinner.

Explanation:

Data

dinner = 18:00

left = 12:00

speed = 45 mph

distance = 300 miles

time = ?

Formula

speed = distance / time

time =  distance / speed

time = 300 / 45

time = 6.7 hours

Then

from 12:00 to 18:00 there are 6 hours

Marc won't be on time.

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify
