Can someone tell me the full answers for this

The span of time between one new Moon and the next is called a lunar cycle, lunation, lunar month, or synodic month and on average lasts for 29.53059 days. This translates to 29 days, 12 hours, 44 minutes, and 3 seconds.

Explanation:

This means you should divide the bolded number by how many phases the question is asking. Since that number is 4, divide 29 by 4. This equals to about 7 and some decimal points that represent the hours, minutes, and seconds. Because the measurement of time that we are using is days, and we can conclude that's there is about 7 days in between, we know that there is about a week in between those moon phases.
