Johns dog slept for 3 hours if the dog snored every 1/3 of an hour how many times did he snore
Licemer1 [7]
The dog snored nine times. 1/3 of an hour is every 30 minute interval. 30 min + 30 min = 1 hour. Multiply this x3, and the answer is nine. A simpler way of thinking about this is 3 x 3 or 3 squared.
