You can put this solution on YOUR website!
let the time taken by the train equal to T hours.

the time taken by the plane is equal to 1/8 of this plus 20 minutes.

that's equivalent to T/8 + 20/60 = T/8 + 1/3 hours.

that's your answer to part B.

if the train takes 12 hours, then the plane takes 12/8 + 1/3 hours.

that's equivalent to 1 and 1/2 + 1/3 hours which is equivalent to 1 and 5/6 hours.

that's your answer to part A.
