Mercury · Answer

this is similar to the other question I worked out

you can write one equation for time (x + y = 7 hrs) and another equation for distance (80x + 30y = 485) where x is the # of hours going fast and y is the # of hours going through the dust storm. (if you're having trouble deriving or solving these please let us know, we want to help you)
