math time and speed question

If you graph the numbers, it should be able to tell you who walked faster. I would graph 18 minutes multiple times until it reaches past 132. I would also put the minutes as the x axis and the miles as the y axis. I'm not really sure if this would be correct, but that is how I would figure it out. I apologize ahead of time it is isn't :)

if someone walked 5.5 miles in 132 minutes and someone else walked 0.6 miles in 18 minutes who walked faster?

5.5/132=0.04167 miles per minute.

.6/18=0.0333 miles per minute. Or you can do this by making either their miles or their minutes equal:

132/18 X .6=4.4 miles walked in 132 minutes for the second walker. So, now you can compare like times: 5.5 miles in 132 minutes vs. 4.4 miles for the second walker in the same 132 minutes.

So, obviously the person that covered 5.5 miles in 132 minutes walked faster than the other who walked 4.4 miles in the same amount of time.

Or, you could the reverse:

132/5.5=24 minutes to cover 1 mile.

18/.6    =30 minutes to cover 1 mile.

So, obviously the person that walked 1 mile in 24 minutes walked faster        than the person who walked 1 mile in 30 minutes.
