The temperature at moon is 75 degrees Fahrenheit. The temperature drops 3 degrees every half hour. What is the temperature at 4p.m.

To find the temperature at 4 p.m., we need to determine how many half-hour intervals have passed since the temperature was recorded at 75 degrees Fahrenheit. Then we can calculate the temperature drop during that time.

Let's break it down step by step:

1. Determine the time difference: We need to find out how many half-hour intervals have passed between the recorded temperature and 4 p.m. The temperature drop is 3 degrees per half hour.

Given that there are 12 half-hour intervals between 12 p.m. (noon) and 4 p.m., we can calculate the number of half-hour intervals from the temperature recording time to 4 p.m.

Since half an hour has passed between 12 p.m. and 12:30 p.m., and we need to consider the time from 12:30 p.m. to 4 p.m., there are 11 half-hour intervals between the recorded temperature and 4 p.m.

2. Calculate the temperature drop: We know that the temperature drops by 3 degrees every half hour. Multiply the number of half-hour intervals by 3 to determine the total temperature drop.

11 half-hour intervals × 3 degrees = 33 degrees

3. Calculate the temperature at 4 p.m.: Subtract the total temperature drop from the recorded temperature to find the temperature at 4 p.m.

75 degrees - 33 degrees = 42 degrees Fahrenheit

Therefore, the temperature at 4 p.m. would be 42 degrees Fahrenheit.

from noon to 4 is 4 hours

4 x 3 = 12 degrees dropped.
75-12 =
