Answer: - 5
Explanation:
1) Some information in the question is missing: the height of the roller coaster at the bottom of the drop.
2) Here is the complete question: "Across a horizontal distance of 25 feet, a roller coaster has a steep drop. The height of the roller coaster at the bottom of the drop is -125 feet, compared to its height at the top of the drop. What is the average amount that the roller coaster's height changes over each horizontal foot"
3) Now, you can calculate the average amount that the roller coaster's height changes over each horizontal foot, using this formula:
Average change = [change in height] / [change in horizontal]
4) Change in height = [final height - initial height] = - 125 feet
5) Change in horizontal distance = 25 feet
6) Answer: - 125 feet / 25 feet = - 5.
The negative sign means that the height decreased.

Given :
A complex number z = 10 - 13i .
To Find :
Which quadrant will the complex number (10 - 13i) be found.
Solution :
Coefficient of real part of complex number, r = 10.
Coefficient of imaginary part of complex number, i = -13.
Since, the coefficient of imaginary part is -ve and real part is +ve .
Therefore, the complex number is in 4th quadrant.
Hence, this is the required solution.
3 meters per minute is the rate.
7.5/3 = how much minutes he walked.
7.5/3 = 2.5
Answer: It walked for 2.5 minutes.
