Question

Time at place A located on 70 degree east longitude is 10 pm. What is the time at place B located on 40 degree east longitude?

Answer 1

Answer:

8 pm

Explanation:

• as for every 15 degress there is change of 1 hr

as you move from east to greenwich mean time (GMT)  ,time will decrease and viceversa .

• time at  70 degree east = 10pm

• difference in degree between 70 and  40 degree = 30 degree.

         hence it will make 2 hrs difference.

• but will it be 8 pm or 12 am it depends on whichnside you are moving i.e towards GMT  or away from it.

• in above case 40 degree E will towards GMT hence it will decrease from 70 degree. hence you will get 8 pm at 40 degree east.
