I know u have use the equation to find the orbital speed. Did everyone get 179 km per hour for the speed?
That was what I was thinking. I can't tell if it was 179 km/hour because I think that the orbital radius was 250000km, however, another person told me it gave the circumference as 1500000km and so it would be 17000 km/hour which seems more correct. I can't remember which one I wrote down. If you are certain that the orbital radius they gave was 250000km and the time period was 365 days, then yes it was.

The circumference was definitely 1.5 x 10^6 km (1,500,000km)
I reckon the grade boundary will be 143 to 146 for Paper 1 & 2, so that will be around 95 - 97 for just paper 1, but you can still get the A* if you do really well in the paper 2.

but it was km/hr so didnt you have to convert 365 days to hours

Ah no I read the question wrong. So 150000000 was the circumference and not the radius.
