Marla drives her car to school each day. If it takes her 12 minutes to drive one way, how many hours a week does Marla spend driving? (Express the answer in decimal form.)

one way that might help you get the answer is (12+12)x5 because only one way is 12 minutes and she goes to school five days a week and round trip she spends 24 minutes

To convert it to hours, divide by 60

An automobile maker has an order for 7,500 new cars to be delivered in one week. Each car must be fitted with a new hood ornament that requires 1 hour and 15 minutes to install. Assuming the factory operates on a standard workweek shift (8 hours per day for 5 days), how many workers must be assigned this job to meet the deadline?
