BRAINLIESTTT ASAP!

If from the low tide to the high tide there was a break of 6h and 4m than the next tides will happen at the same rate:

8:35 + 6:04 = 14:39 = next low tide.
14:39 + 6:04 = 20:43 = next high tide.

Note that two same tides occur about 12h to 12h and 25m apart, and that is the case here:

14:39 - 2:31 = 12:08 hours apart
20:42 - 8:35 = 12:07 hours apart.

Hope it helped,

Happy homework/ study/ exam!
