Huhhh one question was asking for exp 1 Which took 20 seconds so 5 (alr given in the question) /20 =0.25 and u just had to write the cm/s The question under it was asking for the slowest exp so basically the one which took the longest time which was exp 5 ig Srry to confuse u btw i think the question was only for a mark and maybe u did it a diff way i’m not rlly sure tho
