Answer:
![\frac{867}{2000}](https://tex.z-dn.net/?f=%5Cfrac%7B867%7D%7B2000%7D)
Step-by-step explanation:
![\frac{0.4335\cdot \:10000}{10000}](https://tex.z-dn.net/?f=%5Cfrac%7B0.4335%5Ccdot%20%5C%3A10000%7D%7B10000%7D)
![\frac{4335}{10000}](https://tex.z-dn.net/?f=%5Cfrac%7B4335%7D%7B10000%7D)
![\frac{867}{2000}](https://tex.z-dn.net/?f=%5Cfrac%7B867%7D%7B2000%7D)
Answer: 15 mph
Step-by-step explanation:
Given: Time taken to travel uphill to the toy store= 12 minutes![=\frac{12}{60}=0.2\ hour](https://tex.z-dn.net/?f=%3D%5Cfrac%7B12%7D%7B60%7D%3D0.2%5C%20hour)
Let d be the distance(in miles) between the home and toy store.
Also,
![\\\Rightarrow10=\frac{d}{0.2}\\\Rightarrow\ d=0.2\times10=2](https://tex.z-dn.net/?f=%5C%5C%5CRightarrow10%3D%5Cfrac%7Bd%7D%7B0.2%7D%5C%5C%5CRightarrow%5C%20d%3D0.2%5Ctimes10%3D2)
Thus, distance from home to toy store= 2 miles
When she turn back, to home distance remains same.
The time taken by her to come back at 30 mph speed=
![Time=\frac{Distance}{speed}=\frac{2}{30}=\ hour](https://tex.z-dn.net/?f=Time%3D%5Cfrac%7BDistance%7D%7Bspeed%7D%3D%5Cfrac%7B2%7D%7B30%7D%3D%5C%20hour)
Now, the average speed =![\frac{\text{Total distance}}{\text{Total time}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BTotal%20distance%7D%7D%7B%5Ctext%7BTotal%20time%7D%7D)
![=\frac{2+2}{0.2+\frac{2}{30}}\\=\frac{4}{\frac{6+2}{30}}\\=\frac{4\times30}{8}=\frac{120}{8}=15\ mph](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%2B2%7D%7B0.2%2B%5Cfrac%7B2%7D%7B30%7D%7D%5C%5C%3D%5Cfrac%7B4%7D%7B%5Cfrac%7B6%2B2%7D%7B30%7D%7D%5C%5C%3D%5Cfrac%7B4%5Ctimes30%7D%7B8%7D%3D%5Cfrac%7B120%7D%7B8%7D%3D15%5C%20mph)
