Acar travels 350 miles on 20 gallons of gasoline. how many gallons will be used to travel 875 miles under the same condition? explain how you did it

A car can travel for a distance of 350 miles in = 20 gallons
The car can travel for a distance of 1 mile in = (20/350) gallons
                                                                        = 2/35 gallons
Then
The same car can travel for a distance of 875 miles in = (2/35) * 875 gallons
                                                                                        = 1750/35 gallons
                                                                                        = 50 gallons
So it can be seen that 50 gallons of gasoline is required to travel for a distance of 875 miles. I hope the procedure is clear enough for you to understand.
