Answer 1

John read for 3 hours

Explanation:

Mike read 6 hours. Sasha doubled the reading time so 3*2=12. Tom read half of that time, so it is the same as Mike which is 3. John read half of Tom's time, so 6 divided by 2 is 3.

Answer 2

John read for 3 hours

Explanation:

j = 0.5t; t = 0.5s; s = 2m; m = 6

s=2(6), s=12; t=0.5(12), t=6; j=0.5(6), j=3
