Question
Trey started to run on a treadmill after setting its timer for 64 minutes. The display says that he has finished 54% of his run. How many minutes have gone by? Round your answer to the nearest tenth.
Solution
To find out how many minutes have gone by, we need to calculate 54% of the total time set, which is 64 minutes.
Step 1: Convert the percentage to a decimal. To do this, divide the percentage by 100. So, 54% becomes 0.54.
Step 2: Multiply the total time by the decimal. So, 64 minutes * 0.54 = 34.56 minutes.
Step 3: Round the result to the nearest tenth. So, 34.56 minutes rounds to 34.6 minutes.
So, approximately 34.6 minutes have gone by.
