# How many seconds in day?

There are 86400 seconds in 1 day. Explanation: As a teacher, it is important to understand the mathematical concept behind this calculation. One day is equivalent to 24 hours, and each hour contains 60 minutes. Additionally, each minute has 60 seconds. Therefore, to find the total number of seconds in a day, we need to calculate the number of minutes in a day. This can be done by multiplying 1 day by 24 hours per day, and then by 60 minutes per hour. So, the formula for calculating the number of minutes in a day is as follows: 1 day × 24 hours/day × 60 minutes/hour = 1440 minutes. This means that there are 1440 minutes in one day. To find the number of seconds in a day, we need to multiply the number of minutes by the number of seconds per minute. Therefore, the formula for calculating the number of seconds in one day is: 1 day × 1440 minutes/day × 60 seconds/min = 86400 seconds. Thus, there are 86400 seconds in one day. It is essential for students to understand these calculations since it relates to time management, and helps them to plan their activities and daily routines effectively.
