What is meaning of “in...day(s), month(s), year(s) and etc?
If I make these sentences below, what would be the meaning of them.
-In 100 years, people will travel to the Mars easily.
-In 10 years, people around the world will probably use automatic car.
I have studied about making predictions in English book. Then I am confused about the meaning of in...day(s), month(s), year(s). Thank you for your help!

  • Have a look at the definition of "in" in a dictionary - for example, definition #3 here. Then explain what exactly do you find confusing. – michael.hor257k Dec 2 '18 at 13:31
  • "within" is also commonly used. – user3169 Dec 3 '18 at 0:16

Here 'in' is a preposition which means after a particular length of time. So

In 100 years, people will travel to the Mars easily.

Means after a century, people will travel to Mars easily.

Another example:

She learnt to drive in three weeks.
