Tommy and his family are touring Chicago. They want to visit the Willis Tower, hang out at Navy Pier, and shop on Michigan Avenue before their dinner reservations at 3:30 P.M. They plan to spend 1 hour and 15 minutes at the Willis Tower, 2 hours at Navy Pier, and 1 hour and 15 minutes shopping. What is the latest time Tommy's family can start their tour of Chicago and still make it to dinner on time?

Add the times to find the total elapsed time.

 

1 h + 15 min + 2 h + 1 h 15 min = 4 h 30 min

 

Now find 4 hours and 30 minutes before 3:30 P.M.

 

Count back by hours to find 4 hours before 3:30 P.M. This is 11:30 A.M.

 

Now subtract 30 minutes from 11:30 A.M. This is 11:00 A.M.

 

Tommy's family should start their tour of Chicago at 11:00 A.M.
