I think it is 20 seconds because when you multiply six times x, you get twelve. And in this case, the x equals two. So, because you multiplied two to six, you do the same thing to the ten seconds, which is twenty. Sorry if this is the wrong answer.
1/4 would be * 2 since 4*2=8 so 1*2=2 so the answer is 2/8 in total
True the variable in the expression is y
