## ETA: Estimated Time of Arrival

ETA stands for Estimated Time of Arrival. It is also called as Expected Time of Arrival. ETA is the one of a popular internet slang now a day.

It is used to show the amount of time remaining for a particular entity to arrive or something is expected to be done. This entity can be a train, airplane, bus, ship, letter, courier anything that you expect to arrive. This term is commonly used to show the date the time at which a ship is supposed to arrive at the port. The time is specified in the form of a particular date with expected time in hours and minutes. The Expected time is measured from the past experiences and with the help of a formula. For example, in public transport, the estimated time of arrival of trains, buses, planes etc. is calculated on the basis of their static time table, traffic intensity and current and past record of movements.

Let's take an example to understand it well:

Suppose you are travelling from Delhi to Agra by train. The distance between Delhi to Agra is 180 km and the average speed of the train is 60 km/hour. So if you start your journey at 6am your estimated time of arrival (ETA) at Agra will be 9 am.

This is the formula to calculate the ETA:
