Answer:
20 minutes
Step-by-step explanation:
Remember that
![1\ h=60\ mi](https://tex.z-dn.net/?f=1%5C%20h%3D60%5C%20mi)
we know that
Hector has 3/4 hour to spend his homework
Convert to minutes
![\frac{3}{4}(60)=45\ min](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%2860%29%3D45%5C%20min)
so
1) He wants to spend 1/3 of this time on math homework
To find out the time on math homework, multiply 45 minutes by 1/3
![45(\frac{1}{3})=15\ min](https://tex.z-dn.net/?f=45%28%5Cfrac%7B1%7D%7B3%7D%29%3D15%5C%20min)
2) He wants to spend 10 minutes of his time on reading homework
3) He wants to spend the remaining time on science homework
The time spend on math homework plus the time spend reading homework, plus the time spend on his science homework must be equal to 45 minutes
Let
x ----> the time spend on his science homework
![15+10+x=45](https://tex.z-dn.net/?f=15%2B10%2Bx%3D45)
Solve for x
![25+x=45\\x=45-25\\x=20\ min](https://tex.z-dn.net/?f=25%2Bx%3D45%5C%5Cx%3D45-25%5C%5Cx%3D20%5C%20min)
