Sandra and Heather hung out at the mall on Saturday. They spent 45 minutes shopping for clothes and 1 hour and 5 minutes at the food court. Then they spent 2 hours and 55 minutes at the video arcade before heading home. It was 2:40 P.M. when Sandra and Heather left the mall. What time did they start shopping for clothes? Include A.M. or P.M. in your answer (for example, 11:58 A.M.).
45 minutes shopping + 1 hr 5 minutes food court + 2hr 55 minutes at the arcade = total time spent at the mall. 4 hrs 45 minutes is the total time spent at the mall. If they left at 2:40 they arrived at 9:55am.
