Driving from Wilson,WY to Grand Teton National Park – how long will it take?

Google Maps is saying it will take 30-40 minutes, but the hotel website says the park entrance is only 5 miles away. Can anyone help?

The town of Jackson, WY is approximately 5 miles away however the Moose entrance station to Grand Teton National Park is approximately 20 miles from Wilson. That drive will take about 25 to 30 minutes.
