Respuesta :

The match started at 10:45

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
