Answer 1

Tom ran the 100 meter dash this year in approximately 12.355 seconds.

Step-by-step explanation:

To find out how fast Tom ran the 100 meter dash this year, we need to add the improvement in his time to his time from last year. Last year, he ran the race in 11 5/6 seconds, which is equivalent to 11 + 5/6 = 11.83 seconds.

This year, he improved his time by 0.525 seconds.

Adding this improvement to his time from last year, we get 11.83 + 0.525 = 12.355 seconds. Therefore, Tom ran the 100 meter dash this year in approximately 12.355 seconds.
