Question

The Himalayan Mountains have been growing slowly for about 50 million years. Using the same method, find out how many human lifetimes have passed since the Himalayan Mountains began to grow.
Using your answer from the previous question complete the statements to find out how many human lifetimes have passed since the Himalayan Mountains began to form.
"Let h represent the number of human lifetimes.
h = $\frac{50,000,000}{80}$50,000,00080 =

In other words, [625000] human lifetimes have passed since the Himalayan Mountains began to form."

Answer 1

To find out how many human lifetimes have passed since the Himalayan Mountains began to grow, we can use the formula:

\[
h = \frac{\text{total years}}{\text{average human lifetime}}
\]

Given:
- The total years since the Himalayas began to grow = 50,000,000 years
- The average human lifetime = 80 years

Now, substituting these values into the formula:

\[
h = \frac{50,000,000}{80}
\]

Calculating it:

\[
h = 625,000
\]

So, in other words, **625,000** human lifetimes have passed since the Himalayan Mountains began to form.

To complete the statements:

"Let h represent the number of human lifetimes.
h = \(\frac{50,000,000}{80}\) = 625,000.
In other words, 625,000 human lifetimes have passed since the Himalayan Mountains began to form."
