Five hours
time = distance / speed time = 125/75 = 1.66 hours = 1 hr 40 min
60/75 x 60 = 48 minutes
It would take five hours.
If you are going at 50km per hour then it would take you 1 hour and 36 minutes to travel 80km. This time will only happen if you travel at 50km the entire time.
If you follow the A92, it's about 50km, and should take about 45min.
50km/60 min is 0.83 km in each minute, so divide to get minutes from km/min -- 20 km/0.83km/min = 24 minutes
Divide how far it has traveled by 50 to get the time in hours.
About 1 hour at 55 mph hour - less if you drive faster, more if you drive slower.
