Sig fig hw question please help?

When you perform the subtraction operation, you get an answer of 0.66. However, since the smallest number of decimal places you have (between the numbers in the operation) is 1, the answer for the number in the denominator is 0.6, which has ONE significant figure. Therefore, after performing the division operator your answer should only have ONE significant figure, making the answer 0.06 m/s.
