Answer:
11:00
Step-by-step explanation:
To find out when the chess match started, we need to subtract the duration of the match 3 1/4 hours from the finishing time (14:10)
first lets convert 3 1/4 hours to a decimal
3 1/4 = 3 + 1/4 = 3.25 hours
we need to subtract 3 hours and 15 minutes (which is 3.25 hours) from 14:10
14:10-3.15
14:10-3.10= 11.00
so the match started at 11:00
