John read half of the time that tom read. tom read that half of the time sasha read. sasha read twise as long as mike. if mike read 6 hours, how long did john read?

John read for 3 hours

Step-by-step 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

John read for 3 hours

Step-by-step 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.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
