Answer:
58 seconds
Step-by-step explanation:
100 meters in all
Exact calculations:
There are 2 half parts and first half in 27.8 seconds and second in 30.12 seconds so in all it took 27.8+30.12 = 57.92 seconds
Best estimates
27.8 ≈ 28
30.12 ≈ 30
Lily swims a 100 meter race in about 28+30 = 58 seconds
