Answer:
Time = 3.27s
Explanation:
Time = Distance / Speed
Time = 42.2 / 12.9 = 3.2713
When you multiply the number of significant figures in the result is the same as the number with the least significant figures.
In this case 42.2 has 3 significant figures and 12.9 also has 3 significant figures, therefore the answer must have 3 significant figures too.
Time = 3.27 s
