Answer:
Alecia lives farther from school
Step-by-step explanation:
<em>Georgia</em>
we know that
The distance from the school to her home is 67/100 of a mile

<em>Alecia</em>
we know that
The distance from the school to her home is
3/10 of a mile plus 4/10 of a mile
so

Compare the distances

therefore
Alecia lives farther from school
Answer:
divide both sides of the equation by 2/3
Answer:
Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine.Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
