liq [111]

It will take the snail <u>40,271.33 hours</u> (time) to travel 1,171.1 miles (distance) at 0.013 meters per second (speed).

<h3>How are the hours determined?</h3>

The hours that it will take the snail to travel the distance is determined by first converting the miles into meters at 1 mile = 1,609.34 meters.

The speed per second is also converted into speed her hour.

The conversions use the mathematical operations of division and multiplication.

Time = distance/speed.

<h3>Data and Calculations:</h3>

Total distance in miles = 1,171.1 miles

Total distance in meters = 1,884,698.07 meters (1,171.1 x 1609.34)

Speed = 0.013 meters per second

Speed in hours = 46.8 meters per hour (0.013 x 60 x 60)

The number of hours to cover the distance = Total Distance/Speed

= <u>40,271.33 hours </u>(1,884,698.07/46.8)

Thus, it will take the snail <u>40,271.33 hours</u> to cover a distance of 1,171.1 miles at a speed of 0.013 meters per second.

Answer:

The projected world population in 2015 was 8,705,121,030 people.

Step-by-step explanation:

Given that the population of the world in 1987 was 5 billion and the annual growth rate was estimated at 2 percent per year, assuming that the world population follows an exponential growth model, to find the projected world population in 2015 the following calculation must be performed :

5,000,000,000 x 1.02 ^ (2015-1987) = X

5,000,000,000 x 1.02 ^ 28 = X

5,000,000,000 x 1.741024 = X

8,705,121,030 = X

Therefore, the projected world population in 2015 was 8,705,121,030 people.
