John read the quarter of the time that Tom read. Tom read only 2/5 of the time that Sasha read. Sasha read twice as long as Mike. If Mike read five hours how long did John read?
First, we need to calculate how long Sasha read. Since Sasha read twice as long as Mike, she read 2 * 5 = 10 hours.
Next, we need to calculate how long Tom read. Tom read only 2/5 of the time that Sasha read, so he read 2/5 * 10 = 4 hours.
Finally, we need to calculate how long John read. John read the quarter of the time that Tom read, so he read 1/4 * 4 = 1 hour.
Therefore, John read for 1 hour.
