from noon to 4 is 4 hours
4 x 3 = 12 degrees dropped.
75-12 =
4 x 3 = 12 degrees dropped.
75-12 =
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.
