Answer:
1) 30:1
2) 30:1
Step-by-step explanation:
We are given the following information in the question:
Miles-Gas(Gallons): 30 - 1
, 60 - 2
, 90 - 3
, 120 - 4
, 150 - 5
, 180 - 6
, 210 - 7
, 240 - 8
, 270 - 9
, 300 - 10
1) We have to find the ratio of the given problem.


The ratio is 30:1 and it can be read as 30 miles per gallon of gas which means the car covers a distance of 30 miles in 1 gallon of gas.
2) If we divide the obtained ration by the second quantity of ratio, then,

The new ratio is 30:1.
This ration is in proportion, when two ratios are equal thy are said to be in proportion.
