Step-by-step explanation:Since an answer was not provided to solve the equation you can only simplify it. You would multiply 3 by -4x to get -12x. You would then multiply 3 by 8 to get 24. You do these first 2 steps because of distributive property. You would add -12x+24. If an answer is not provided you cannot simplify this any further. Hope this helps!
Convert 3 hours and 30 minutes all into minutes so that would be 210 minutes. You then have 169 miles / 210 minutes. Get the denominator to 1 minutes by dividing by 210 to the top and bottom and you'll get .080476 miles / 1 minute which is the answer.
