MIT early action

My october sat score will be available by 26 october . Would I be able to meet the deadline which is the 1st november ?

This answer is on the MIT website. http://mitadmissions.org/apply/freshman/dates

How many days the sat scores will take to reach MIT ? If I send the scores by 26 october via college board , would they arrive on time (1st november) ?

Follow the links on the Admissions webpage that @happy1 gave you:

"Testing Deadlines and Reporting Scores

In order to apply for freshman admission, you must take the required tests on or before the November test date for Early Action or the December test date for Regular Action. These are the latest scores that will reach the Admissions Committee in time for review.

Your scores must be reported to us officially from the testing agency; scores you list on your application and scores appearing on your school transcript will not be considered official.

Please allow plenty of time for your scores to arrive at MIT. Keep in mind that it takes at least 4 to 6 weeks for us to receive SAT scores. We recommend that you list MIT as a school to receive your scores when you take the test. If you are an Early Action applicant, and you take the November test—or if you are a Regular Action applicant, and take the December test—you must list MIT as a school to receive your scores or we will not receive them in time for our review." http://mitadmissions.org/apply/freshman/tests

So yes, sending the October test is fine. Even the November test is timely as long as you choose MIT as a report recipient when you take the test.
