Final answer:
In this case, it would be best to choose the Service Provider with the shortest ETA.
Step-by-step explanation:
In this case, if you have two ETAs over 60 minutes, it would be best to choose the Service Provider with the shortest ETA. This is because the ETA represents the estimated time of arrival, so choosing the Service Provider with the shortest ETA would mean that you are likely to receive the service sooner.
