Answer:
40 kilometres
Step-by-step explanation:
3cm : 10 kilometres
x4 x4
12cm : 40 kilometres
40, because if you have 3 and 10 and 12 is 4 times 3. So you would multiply 10x4 to get 40.
The slope is 2. The y-intercept is 4.
Explanation:
The line constantly goes up to units for every unit that it goes to the right. The y intercept is 4 because it is 4 on the y-axis when x is 0.
R=D/T
130 = r x 11.75
R=130/11.75=11.06
11.06 MPH
