Final answer:
After adding the time Jon spent at the Empire State Building, Central Park, and Times Square, it is determined that Jon and his family went to dinner at 7:20 P.M., which does not match any of the given options.
Step-by-step explanation:
Jon and his family went to dinner after spending a certain amount of time visiting attractions in New York City. To calculate the time when they went to dinner, we need to add the duration of each activity to their start time. Starting at the Empire State Building at 1:40 P.M., they spent 1 hour and 35 minutes there, which brings the time to 3:15 P.M. Then they spent 2 hours and 50 minutes in Central Park, which brings the time to 6:05 P.M. Finally, they spent 1 hour and 15 minutes in Times Square before dinner, which makes the time 7:20 P.M. when they went to dinner.
Therefore, the correct answer is d) 7:55 P.M. However, there appears to be a discrepancy in the options provided as none of the options match the calculated time of 7:20 P.M. there might have been an error in the options listed or in the calculation.
