Determine the distance from school to her home
Given.
[When going to school]
![Speed = 6mph](https://tex.z-dn.net/?f=Speed%20%3D%206mph)
Represent time with t
Distance is calculated as:.
![Distance = Speed * Time](https://tex.z-dn.net/?f=Distance%20%3D%20Speed%20%2A%20Time)
![Distance = 6 * t](https://tex.z-dn.net/?f=Distance%20%3D%206%20%2A%20t)
![Distance = 6t](https://tex.z-dn.net/?f=Distance%20%3D%206t)
[When coming back from school]
![Speed = 35mph](https://tex.z-dn.net/?f=Speed%20%3D%2035mph)
![Time = \¾\ hour\ lesser](https://tex.z-dn.net/?f=Time%20%3D%20%5C%C2%BE%5C%20hour%5C%20lesser)
This implies that she spends t - ¾hr when coming back from school.
So,
becomes
![Distance = 35 * (t - \¾)](https://tex.z-dn.net/?f=Distance%20%3D%2035%20%2A%20%28t%20-%20%5C%C2%BE%29)
![Distance= 35(t - \¾)](https://tex.z-dn.net/?f=Distance%3D%2035%28t%20-%20%5C%C2%BE%29)
[Equate both expressions of distance]
![35(t - \¾) = 6t](https://tex.z-dn.net/?f=35%28t%20-%20%5C%C2%BE%29%20%3D%206t)
[Open Bracket]
![35t - 35 * \¾ = 6t](https://tex.z-dn.net/?f=35t%20-%2035%20%2A%20%5C%C2%BE%20%3D%206t)
![35t - 26.25 = 6t](https://tex.z-dn.net/?f=35t%20-%2026.25%20%3D%206t)
[Collect like terms]
![35t - 6t = 26.25](https://tex.z-dn.net/?f=35t%20-%206t%20%3D%2026.25)
![29t = 26.25](https://tex.z-dn.net/?f=29t%20%3D%2026.25)
[Solve for t]
![t = \frac{26.25}{29}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B26.25%7D%7B29%7D)
![t =0.91](https://tex.z-dn.net/?f=t%20%3D0.91)
[Substitute 0.91 for t in]
![Distance = 6t](https://tex.z-dn.net/?f=Distance%20%3D%206t)
![Distance = 6 * 0.91](https://tex.z-dn.net/?f=Distance%20%3D%206%20%2A%200.91)
![Distance = 5.43\ miles](https://tex.z-dn.net/?f=Distance%20%3D%205.43%5C%20miles)
<em>Hence, the school is 5.43 miles from her home</em>
