Question

suppose high tides for a location occur at 3:30 a.m. and 4:00 p.m. when would a low tide likely occur? (1 point)
○ 12:00 p.m.
○ 9:45 a.m.
○ 1:00 a.m.
○ 3:30 p.m.

Explanation:

Step1: Find time between high tides

The two high tides are at 3:30 a.m. and 4:00 p.m. Calculate the time difference: from 3:30 a.m. to 4:00 p.m. is 12 hours and 30 minutes.

Step2: Determine low tide interval

The time between a high tide and the next low tide is approximately half of the time between two high tides. Half of 12 hours 30 minutes is 6 hours 15 minutes.

Step3: Calculate low tide time

Add 6 hours 15 minutes to 3:30 a.m.: 3:30 a.m. + 6 hours 15 minutes = 9:45 a.m. Check other options: 12:00 p.m. is 8.5 hours from 3:30 a.m., 1:00 a.m. is 2 hours before 3:30 a.m., 3:30 p.m. is 12 hours from 3:30 a.m. (high tide again), so 9:45 a.m. is correct.

Answer:

B. 9:45 a.m. (assuming the options are labeled as A:12:00 p.m., B:9:45 a.m., C:1:00 a.m., D:3:30 p.m. as per typical multiple - choice formatting)
