How long is one million years? It helps to think about this in terms of numbers that are more familiar to us. For example, how many human lifetimes are in one million years?

Step 1. Assume the average human lifetime is 80 years. The question asks how many human lifetimes are in 1 million years, so we need to find out how many times 80 divides into 1,000,000. Let h represent the number of human lifetimes.

Step 2. h = 1,000,000 / 80 = 12,500. There are 12,500 human lifetimes in 1 million years.

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.
