Answer:
1 and 3/7 hour
Step-by-step explanation:
Every hour they get 140 miles closer (100 + 40). So you divide 200 by 140 which gets you 1.42... or 1 and 3/7 of an hour.
y=-7/5x-15
First tables blanks are 160, 195, 230, 300
The rate of change would be 35/1 cos the cost is going up by 35 and the months are going up by one
The second tables first row is 1 2 3 4 5, the second row is 5 7 9 11 13
