You had to express the equation in the form ax+by=c, not by+ax=c

I'm not entirely sure but I'm fairly confident you had to differentiate the first one a second time because you are finding velocity not speed... And yeah the second part was definitely 2

In the order of differentiation it is distance speed acceleration, velocity is the vector equivilant to the scalar speed.

That was the question: Make t the subject of the equation "m=t+1/t+2". I think it was either question 15 or 17
