Answer:
2/3 hour
Explanation:
lets say English takes x hour to complete such that Math will take twice as long which is 2x hour. It takes 2 hours to complete both English and Math. So we can write the following equation:-
x+2x=2
or, 3x=2
or, x=2/3
Therefore, English takes 2/3 hour to complete (which is 40 minutes)
And Math takes 4/3 hour to complete (which is 80 minutes)
