Depends what you are using it for! If calculating a MINIMUM such as the braking distance then you should ROUND UP to 45; if you are using it to prove that you can achieve a headway then ROUND DOWN to 44.
Actually it is best to keep the significant figures within calculations and only do the rounding at the end.
Yes you are allowed a basic (non-programmable) calculator; it is not a test of mental arithmetic.

I am planning to write module 2 this year. I have few doubts in that.
If train speed is 160KMPH, if we convert it in to m/s we will get it as 44.444m/s. Wether we have to go with 44.4m/s or 44m/s in the exam.
And calculator is allowed in the exam or not?
with regards,
