Part A: The rounded time for the athlete's 100 meter sprint is 13.2 seconds.
Part B: To round the time to the nearest tenth, we look at the hundredth place value. In this case, the hundredth place value is 4. Since it is less than 5, we round down the tenths place value to 2. Therefore, the rounded time is 13.2 seconds.
Part A: The rounded time to the nearest tenth for the high school athlete running the 100 meter sprint in 13.245 seconds is 13.2 seconds.
Part B: To arrive at the answer, we need to understand the rounding rule for rounding to the nearest tenth. The rule states that if the digit in the hundredth place (the second decimal place) is 5 or greater, we round up the digit in the tenth place (the first decimal place). If the digit in the hundredth place is less than 5, we round down the digit in the tenth place.
In this case, the digit in the hundredth place is 4, which is less than 5. Therefore, we round down the digit in the tenth place, which is 2. Hence, the rounded time to the nearest tenth is 13.2 seconds.
