A helicopter's altitude changes -28.125 ft in 3.75 seconds. What is the average change in the helicopter's altitude each second (per second)? Explain your thinking AND/OR show your work.
HINT: To find the average change per second divide the total change by the total seconds. This helps you find
an equivalent ratio.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
