Answer: 4.5 minutes.
Step-by-step explanation:
1. You have the following information given in the problem above:
- Erica runs [tex]\frac{1}{6}km[/tex] in a minute.
- The school is [tex]\frac{3}{4}km[/tex] away from her home.
2. Therefore, to solve the exercise you must multiply [tex]\frac{3}{4}km=0.75km[/tex] by 1 minute and divide this by [tex]\frac{1}{6}km=0.166km[/tex], as following:
[tex]x=\frac{(0.75km)(1min)}{(0.166km)}\\x=4.5min[/tex]
3. Therefore, the result is 4.5 minutes.
