60 is definitely not the answer as this would be 1 sig figure.

61 defo, my uncles a maths teacher and i checked with him
but if it was 59.419 it could be 60 as in this case a zero would count

It *is* 60. Just because the second figure is a 0, doesn't mean it's not significant. In this case, it is. If you're not sure of this, imagine what if the problem had been to round 60.000 to 2 sig figs - this time there would be no other figures, so it would have to be 60.
Unfortunately several answers have claimed it is 61. It can never be 61 - you can't round up from 59 point anything to 61, you would always round to the next whole number, which in this case is 60.

IT IS DEFINITELY 60.
To round to significant figures you start at the first non-zero number on the left hand side. In this case it is 5. The second significant figure is 9. The third significant figure is 8. Since this is > 5 you round up the second significant figure of 9 to 10 which of course gives 60. Notice the 4th and 5th figures (1 and 9) are irrelevant in this calculation.

Lots of people have the same problem rounding to sig figs. Can you identify the 2nd sig fig in 376 ? It`s the 7, which is 7 tens, so another way of asking the same question [in this case] would be, "round 376 to the nearest 10" The answer being 380. The difficulty that was apparent was the inability to identify the asked for figure of significance, and then relate it to the question. Consider 0.0009283 The first figure of any significance, or value is the 9, the zeros are called zero place holders. the 2nd s.f. is the 2, the 3rd 8, and the 4th 3. To write this number to [say] 3 s.f. is to go to the 8, and then round the number in the usual way, giving 0.00093. Another example, "round 23 592 to 3 s.f." The 3rd s.f. is is the 5, which is 5 hundreds, so you`re being asked to round the number to the nearest hundred, giving 23 600. I do hope this clarifies it for you, Twiggy.

It is 60 as in this case the zero is significant. Putting it in scientific notation removes any ambiguity:
= 6.0 X 10^1

60 as it is 59 rounded up due to the 8 in .8
significant figures are not necessarily after the decimal!

60 to 2 significant figures
59.82 to 2 decimal places

round to two significant figures? -- 60
OR round to two significant decimal points? -- 59.82

surely it is not a rounding, sig fig means just that - show the 2 figures, rounding doesnt come into it
