How long would the journey from my hotel take to Zhujiajiao Watertown?

I am staying at Chuanhuang road, Chuansha Town in Pudong.
The distance to the town is nearly 45 miles (72km). Take metro line 2 from Chuansha Station to People's Square Station, Exit 1. Then, take Huzhu Express Line to the water town from Pu'an Road, East Yan'an Road Station.
