Question

A hot air balloon descended 99.6 meters in 12 seconds. What was the balloon's average rate of descent in meters per second?

Answer 1

99.6 divided by 12 is 8.3 so the answer is 8.3

Answer 2

Answer: 8.3 meters per second.

Step-by-step explanation:

Given : A hot air balloon descended 99.6 meters in 12 seconds.

then, the average rate of descent is given by :-

$\text{Average rate of descent}=\dfrac{\text{\text{Distance descended }}}{\text{Time}}\\\\\Rightarrow\ \text{Average rate of descent}=\dfrac{99.6}{12}\\\\\Rightarrow\ \text{Average rate of descent}=8.3$

Therefore, the balloon's average rate of descent in meters per second = 8.3 meters per second.
