To find out how much faster you were in Race 3 than in Race 1, we need to subtract the swim time of Race 3 from the swim time of Race 1.
-
Identify the times:
- Race 1: 14.05 minutes
- Race 3: 12.95 minutes
-
Set up the subtraction: \[ 14.05 - 12.95 \]
-
Perform the subtraction: \[ 14.05 - 12.95 = 1.10 \]
So, you were 1.10 minutes faster in Race 3 than in Race 1.
- Check the answer using estimation:
- For estimation, round Race 1's time to 13 minutes.
- Then do the estimation: \[ 13 - 12.95 \approx 1 \text{ (this is very close)} \]
Thus, the complete statement would be:
"We're asked to find 'how much faster,' and that is a subtraction problem, which means subtraction.
14.05 - 12.95 = 1.10.
We were 1.10 minutes faster in the 3rd race than in the first.
Check the answer by using estimation: 13 - 12.95 = 1 minutes, which is close to the actual answer of 1.10 minutes."
