Five laps? I don’t know if you meant to put that the track is a mile around, but if the track is a half mile around, an athlete would have to run 10 laps around the track to run 5 miles.
X=5/y, so x would be how many laps the athletes run, and y would be the length of the track. Hope this helps

You are correct in thinking that the columns of the first matrix must match with the rows of the second matrix.
So for example, we can multiply a 1 x 5 matrix with a 5 x 7 matrix. The two matching '5's are directly what make multiplication possible in this case. For your problem, the first two '3's match and multiplication is possible.
The rows of the first matrix don't need to match with the columns of the second matrix.

For this question you should first find a pack of one toilet roll for each cost so you can say :
if 9 toilet rolls cost 4.23 so 1 toilet roll is : 4.23/9 = 0.47
and if 4 toilet rolls cost 1.96 so 1 toilet roll is : 1.96 /4 = 0.49
so 0.49 is greater than 0.47 so a pack of 9 toilet rolls gives the better value for money :)))
i hope this is helpful
have a nice day
