It was 990 and there is a big difference b/w 990 and 975 so I used Pythagoras. Anyways, both should be correct.

Yes.
I did both.
They won't deduct any marks I guess because they never specified that we cannot use the scale.

calculate can also mean measuring the distance and then multiplying it by 150 to get ans

It's written in the examiner tips that answers by accurate drawing (calculate) will not be accepted. Khair, it doesn't make a difference.

Listen when the speed of an object and its direction in VECTOR FORM is given, how do we find the velocity vector and why? And could we derive a velocity vector if only the bearing if the object and its speed are given? If so how?

Like in j12 p1 Q12. Why can't we take the 3i + 4j as the velocity vector?
