Answer:
45 minutes or .75 of an hour or 3/4 of an hour
Explanation:
if you walk 2 miles in a half-hour (30 minutes) , how long will it take to walk 3 miles. Well the answer is simple, we need to use proportions to solve it though. For example:
=
![(2)/(.5)](https://img.qammunity.org/2021/formulas/mathematics/high-school/dvzupny56m38grebteeakbd95j5etkn3he.png)
therefore, half of .5 is .25
so for someone to complete 1 mile, it takes .25 of an hour. .25 of an hour is 15 minutes. Therefore, the correct simplified proportion is :
![(1)/(.25)](https://img.qammunity.org/2021/formulas/mathematics/high-school/moug9to7mnhxdsjq56xsgl7j52z5pwajeb.png)
Now we need to find out what the denominator (bottom number/time) would be when the numerator (top number of the fraction) is =3.
Since we have the simplified version as a 1, we can just multiply .25 by 3 which is .75, and .75 of an hour is 45 minutes. Therefore the answer is 45 minutes.
