Answer 2

Given,

Longitude of Cairo = 31° E

Time at Greenwich = 12 Noon

To find,

The local time of Cairo.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now, we know that the longitude of Greenwich city is 0°

So, longitudinal difference between Cairo and Greenwich city is = 31° - 0° = 31°

Now,

1° longitudinal difference causes time difference of = 4 minutes

31° longitudinal difference will cause time difference of = 4 × 31 = 124 minutes = 2 hours 4 minutes

Now, as the longitude of Cairo is conveyed in East (E), we have to add the time difference with the local time of Greenwich, to get the local time of Cairo.

Local time of Cairo = 12 PM + 2 hours 4 minutes = 2:04 PM

Hence, the local time of Cairo is 2:04 PM
