Hello!
Since we are given that the speed of sound in the air travels about 343 meters per second, we can multiply 343 meters per second by 5, and then we convert the meters to kilometers.
343 · 5 = 1715 meters per 5 seconds.
1000 meters are equal to 1 kilometer. So, we can divide 1715 by 1000 to convert meters to kilometers.
1715 / 1000 = 1.715
Therefore, the speed of sound in air is about 1.715 kilometers per 5 seconds.
Both are equal y. So you can set them equal to each other
9x+13=2x+48
Subtract 2x from both sides
7x+13=48
Subtract 13 from both sides
7x= 35
X=5

I did the math,This is false.
Hope this helps.
Answer:
<em>75</em>
Step-by-step explanation:
Use a proportion.
4 miles is to 30 minutes as 10 miles is x minutes.
4/30 = 10/x
2/15 = 10/x
2x = 15 * 10
2x = 150
x = 75
Answer: 75
