Kelly works two jobs. She usually works at a retail store for 8 hours during the day and is paid $12.90 per hour by the store. In the evening she works at a restaurant as a manager for 4 hours and is paid $12.20 per hour. How much does she make on average per hour for the day?

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
