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.

Answer:
(a)
(b)62.85cm
Step-by-step explanation:
The growth rate of the shrub is given as:
Where t=time in years, h=height in centimeters
(a)First, we solve for the height h(t) by integrating.
(b)The shrub are sold after 7 years of growth. Therefore, we determine the value of h(t) when t=7 years.
The Shrubs are 62.85cm tall when they are sold.
