hema lives in kolkata india (roughly 90 degree east) she wants to view a football match played in london england(0 degree longitude) the match is scheuld to be telecast on t.v gmt when should she switch on her t.v
India's time is five and a hours ahead to GMT. So if the match starts at 3 o' clock in the evening in London, it will be 8:30 p.m. in India. So Hema needs to switch on the TV at 8:30 in the evening.
