Step1: Identify time - interval for more than an hour

An hour is 60 minutes. We need to consider the time - intervals 61 - 80, 81 - 100, and 101 - 120 minutes from the histogram.

Step2: Read the frequencies for relevant intervals

From the histogram, the frequency for the 61 - 80 minutes interval is 20, for the 81 - 100 minutes interval is 15, and for the 101 - 120 minutes interval is 10.

Step3: Calculate the total number of visits

Add the frequencies: $20 + 15+10=45$.
