Four runners ran the relay, Bill ran his lap in 22.738 seconds, Troy ran in 21.874 seconds, Grace ran in 20.32 second, and Jessica ran 19.047 seconds. Estimate the team's total time to the nearest tenth of a second
Estimate: 84.6
Actual: 83.979 = 84.0
thank you :)
You're welcome.
To estimate the team's total time, we need to add up the individual times of each runner.
Let's start by adding the times for each runner:
Bill's time: 22.738 seconds
Troy's time: 21.874 seconds
Grace's time: 20.32 seconds
Jessica's time: 19.047 seconds
Now, let's add these times together:
Total time = 22.738 + 21.874 + 20.32 + 19.047
Adding these numbers, we get:
Total time = 83.979 seconds
To round this to the nearest tenth of a second, we look at the second decimal place. Since the digit in the second decimal place is 7, which is greater than or equal to 5, we round up the previous digit.
Therefore, the estimated team's total time to the nearest tenth of a second is approximately 84.0 seconds.
