<h2>
Average rate of lowering per minute = 36.67 ft/min</h2>
Step-by-step explanation:
After 10 minutes, the bell is at a depth of 600 ft
After 10 minutes
Depth of bell = 600 ft
After 40 minutes the bell is at a depth of 1,700 ft.
After 40 minutes
Depth of bell = 1700 ft
Time gap = 40 - 10 = 30 minutes
Depth fallen = 1700 - 600 = 1100 ft
We have
Depth fallen = Average rate of lowering per minute x Time gap
1100 = Average rate of lowering per minute x 30
Average rate of lowering per minute = 36.67 ft/min
It is clear that (AB) is a median, and it is obvious that the angle is 90, thus it is an altitude and a perpendicular bisector
Just simply collect like terms.
