She would be able to make 40 in one minute.
To find this, you just divide 120/3 to find how many in one minute.
21.98 rounded to the nearest hundredth is 22
Answer:
![y=x/4+30](https://tex.z-dn.net/?f=y%3Dx%2F4%2B30)
Step-by-step explanation:
Let x be the normal time it takes for her to commute. We know that if she was 30min late, this would had 30 min to the journey. She takes a different route, she can travel four times faster than the normal route.
Therefore the normal time of commute will be 4 times less:
![y=x/4+30](https://tex.z-dn.net/?f=y%3Dx%2F4%2B30)
This equation states that the commute time will be four times faster and adding the 30min that she is late.
½d + 3/8 = -2d
<span>-½d -½d</span>
<span>3/8 = -2 ½d</span>
<span>/(-2

Defined the inverse, inner change the variables and solve for y.
F^-1(x)=x/5-2/5
