Didn't realise that I needed to subtract the 0.5, can you rember the question?
It asked how long he ran for. If you looked at his blood pressure, the first 0.5 was stable. Then it increased (running) then stabled again (stopped). It then went down slowly as he had stopped running and gave it time to drop.
I did notice however it say ".......... minutes" with an S. So either a trick by them or 1 is incorrect.
No, they couldn't use the singular of 'minutes' in the answer could they? I agree with you, it must be 1 technically, but the question was very subjective

Well really they should have done Minute(s) but it's an exam board... They want people to get tricked and fail...

Oh ok,maybe your right, I was under the assumption that the athlete had began excercise and that the O2 and glucose in his blood stream was sufficient for aerobic respiration for 30 seconds.
Although in hindsight, you answer seems more accurate as even standing up increases BP.
