40 I believe because the space of the auto mobile catching up to the train is 4 hours. 4 times 30 is 120 miles so u need to figure out a number that can reach 120 in three hours. 3 times 40 is 120
Answer:
9
Step-by-step explanation:
40 -100 = 60 and 60 percent of 15 is 9
Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
The answer: " 2,000 (feet) " .
___________________________________________
1 measured in. = 24,000 actual inches.
24,000 inches = _?_ ft.
___________________________________________
Note: 12 in. = 1 ft. (exact conversion) ;
24,000 in. * (1 ft. / 12 in) = (24,000 / 12) ft. = 2,000 ft.
_____________________________________________
The answer is: 2000 ft.

Well you can simplify them by dividing by there greatest common factor.
In this case they can both divide by 12!
Thats the biggest number they can divide by...
Soo..
36 ÷ 12 = 3
----------------
48 ÷ 12 = 4
So your answer is 3/4!
Good Luck! :)
