Answer:
126 miles per hour
Step-by-step explanation:
We can draw a triangle and we can use trigonometry to write:
Where a is the distance plane flew in 1 minute
Since, 11,106.13 FEET in 1 MINUTE, to get in hours, we multiply by 60:
11,106.13 * 60 = 66,367.51 feet per hour
Now, to get in miles per hour, we divide by 5280 [5280 feet = 1 mi]
66,367.51 / 5280 = 126.21 miles per hour
To the nearest mph, it would be 126 miles per hour

- The kind of curve obtained is linear.
- The relationship between the variables is direct variation.
- After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.
- The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.
A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a Cartesian coordinate, which are the x-axis and y-axis.
In this exercise, you're required to plot a graph for the data (velocity and time) recorded for an object that is falling from rest.
Based on the graph for the data (see attachment), we can logically deduce the following points:
- The kind of curve obtained is linear.
- The relationship between the variables is direct variation.
- After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.
- The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.
