Question

Do you know the time difference between India and England?

Answer 1

The time difference between India and England is of 5:30 hours.
- If it is noon in England, it is 5:30PM in India because time is ahead in India. It is ahead by 5:30 hours.
- This can be calculated in the following manner:
(i) Difference between $0^{\circ }$ longitude and $82{\frac{1}{2}}^{\circ }$E longitude $=82{\frac{1}{2}}^{\circ }$
(ii) Time in the East is ahead by 4 minutes on passing every meridian.
(iii) Hence, time ahead $82\frac{1}{2}\times 4=330\text{minutes or 5:30 hours}$.
