Taylor swam 3 different heats in the 100m freestyle. The first heat was 29.1 seconds, the second heat was 28.7 seconds, and the third heat was 27.2 seconds. What was the difference between her best time and her worst time?

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

= 28x + 8y + 2 → b
