Calculating Grandfather's Return Trip Time

To calculate the time spent by the grandfather on the return trip, we can use the information provided.

The grandfather spent a total of 1 hour and 20 minutes for the round trip to the polyclinic. He walked to the polyclinic in 25 minutes and spent 48 minutes there.

To find out how much time he spent on the return trip, we can subtract the time spent walking to the polyclinic and the time spent at the polyclinic from the total time for the round trip.

Calculation: 1 hour 20 minutes = 80 minutes Time to the polyclinic = 25 minutes Time at the polyclinic = 48 minutes

Return Trip Time: 80 minutes - 25 minutes (to the polyclinic) - 48 minutes (at the polyclinic) = 7 minutes

So, the grandfather spent 7 minutes on the return trip.
