Answer: 86400 seconds
Step-by-step explanation:
To answer this question, we want to use the appropriate unit conversions provided in the table.
We are tasked to find how many seconds are in one day. This tells us that we want to use the following units:
1 h = 60 min and 1 min = 60 sec
Notice how the units cancel out from numerator to denominator and diagonally. The only unit that would be left is seconds. All we have to do is to plug the formula above and see what the answer is.
Therefore, there are 86400 seconds in a day.
