Answer:
0.25 km/minute.
Step-by-step explanation:
We have been given that Amir can run 15 kilometers in one hour. We are asked to find the number of kilometers Amir can run per minute.
We will use speed formula to solve our given problem.
[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\frac{15\text{ km}}{1\text{hour}}[/tex]
We know that 1 hour equals 60 minutes, so we will substitute 60 minutes in the speed formula.
[tex]\text{Speed}=\frac{15\text{ km}}{60\text{ minutes}}[/tex]
[tex]\text{Speed}=\frac{1\text{ km}}{4\text{ minutes}}[/tex]
[tex]\text{Speed}=\frac{0.25\text{ km}}{\text{ minute}}[/tex]
Therefore, Amir runs 0.25 kilometers per minute.

The ratio of \blueD{\text{kilometers}}kilometersstart color #11accd, start text, k, i, l, o, m, e, t, e, r, s, end text, end color #11accd to \greenD{\text{hours}}hoursstart color #1fab54, start text, h, o, u, r, s, end text, end color #1fab54 is \blueD{15}:\greenD{1}15:1start color #11accd, 15, end color #11accd, colon, start color #1fab54, 1, end color #1fab54.
We want to know the ratio of \blueD{\text{kilometers}}kilometersstart color #11accd, start text, k, i, l, o, m, e, t, e, r, s, end text, end color #11accd to \maroonD{\text{minutes}}minutesstart color #ca337c, start text, m, i, n, u, t, e, s, end text, end color #ca337c.
Hint #22 / 4
We need to convert hours to minutes.
There are \maroonD{60}60start color #ca337c, 60, end color #ca337c minutes in \greenD11start color #1fab54, 1, end color #1fab54 hour.
So, if Amir can run \blueD{15}15start color #11accd, 15, end color #11accd kilometers in \greenD{1}1start color #1fab54, 1, end color #1fab54 hour, then he can also run \blueD{15}15start color #11accd, 15, end color #11accd kilometers in \maroonD{60}60start color #ca337c, 60, end color #ca337c minutes.
Hint #33 / 4
The ratio \blueD{\text{kilometers}}kilometersstart color #11accd, start text, k, i, l, o, m, e, t, e, r, s, end text, end color #11accd to \maroonD{\text{minutes}}minutesstart color #ca337c, start text, m, i, n, u, t, e, s, end text, end color #ca337c is \blueD{15}:\maroonD{60}15:60start color #11accd, 15, end color #11accd, colon, start color #ca337c, 60, end color #ca337c.
Now, we can find an equivalent ratio to find the number of kilometers for \maroonD11start color #ca337c, 1, end color #ca337c minute.
