🔔 At soccer camp, Sally spent 1 hour practising defence and 1 hour and 15 minutes shooting. If the camp ended at 1:15 P.M., what time did it start?
Add the times to find the total elapsed time.
1 h + 1 h 15 min = 2 h 15 min
Now find 2 hours and 15 minutes before 1:15 P.M.
Count back by hours to find 2 hours before 1:15 P.M. This is 11:15 A.M.
Now subtract 15 minutes from 11:15 A.M. This is 11:00 A.M.
Sally’s soccer camp started at 11:00 A.M.
