<span>Distance covered by Mario in 6 hours is 330 miles.
Then, Average speed of Mario is 330 miles divided by 6 hours = 55 miles per hour
so to drive a total distance of 715 miles, it would take him ( 715 miles divided by 55 miles per hour) hours
i.e., 13 hours
so Mario will have to drive for 7 more hours to complete a total distance of 715 miles.</span>
Answer:
can you send a picture of this question, because I can't read all the answers.
Answer:
A human community with high population density and low economic status will have the highest birthrates.
Explanation:
A is not correct because usually, these are populations in countries that are transitioning from one political to another political model, and these populations actually tend to decline, mostly because of immigration.
B is not correct because such populations tend to have low birthrates, often even below the bar for simple replacement of the population.
C is not correct because such populations tend to live in very bad conditions, so despite having relatively high birthrates, they stagnate in their growth.
D is correct because such populations have both the numbers needed and also live in more traditional societies, leading to very high birthrates, as can be seen with Nigeria, Ethiopia, Pakistan, Indonesia, etc.
