Answer 1

the number of minutes from 6:00 pm to 8:00 pm is 120 minutes.

let number of minutes passed from 6;00 pm to right now be x minutes.

then, the number of minutes left for 8:00 pm are 1/4x

Total of the two times is 120 minutes.

=>x+1/4x=120

=>5x/4=120

=> therefore x=96 minutes.

The time left from right now to 8:00 pm is 96/4=24 minutes.

The time left for 8:00 pm 30 minutes ago from now is 54 minutes.
