Question

1. higher order thinking the first - place swimmer’s time in the 100 - meter freestyle at a local swim meet was 1.32 seconds faster than the second - place swimmer. what was the time for the first - place swimmer? what was the difference in time between the second - and third - place swimmers?
2. circle the two subtraction problems that have a difference of 10.2.

12.05−2.03
16.29−6.09
36.1−25.9
22.09−21.07
10.82−9.8

Explanation:

Step1: Find first - place swimmer's time

Subtract 1.32 from second - place time.
$49.33−1.32 = 48.01$

Step2: Find time difference between second and third - place swimmers

Subtract third - place time from second - place time.
$53.65−49.33 = 4.32$

Step3: Solve subtraction problems in 14

$12.05−2.03=10.02$
$16.29−6.09 = 10.2$
$36.1−25.9 = 10.2$
$22.09−21.07=1.02$
$10.82−9.8 = 1.02$

Answer:

First - place swimmer's time: 48.01 seconds
Difference between second and third - place swimmers: 4.32 seconds
Subtraction problems with difference of 10.2: 16.29 - 6.09, 36.1 - 25.9
