How much time does the man take in driving to and from the shopping center?

A man drives from his home at 30 miles per hour to the shopping center which is 20 miles from his home. On the return trip he encounters heavy traffic and averages 12 miles per hour. How much time does the man take in driving to and from the shopping center?

MetroEye: The average speed = DistancetravelledTimeTaken

Time taken for the to-travel = 20miles30milesperhour
Time taken for the from-travel = 20miles12milesperhour

Total time = 2030 + 2012 23 + 5373 hours = 73 * 60 = 140 minutes = 2 hour 20 minutes

The man took 2 hours 20 minutes in driving to and from the shopping center.
