John read half of the time that Tom read. Tom read that half of the time Sasha read. Sasha read twice as long as Mike. If Mike read 6 hours, how long did John read?

m=6

s = 2m = 12
t = s/2 = 6
j = t/2 = 3

To find out how long John read, we need to follow the given information step by step.

First, we know that Mike read for 6 hours.

Next, we are told that Sasha read twice as long as Mike. So, Sasha read for 2 * 6 = 12 hours.

Now, we are told that Tom read half of the time Sasha read. Since Sasha read for 12 hours, Tom read for 12 / 2 = 6 hours as well.

Finally, we are told that John read half of the time Tom read. Since Tom read for 6 hours, John read for 6 / 2 = 3 hours.

Therefore, John read for 3 hours.
