Based on the time at City A and its longitude, the time in City B can be found to be 4 pm.
Every 15° in longitude counts for an hour.
The difference between these two locations in terms of longitude is:
= 90 + 60
= 150°
Both longitudes were added instead of deducted because they are in different hemispheres of East and West.
The difference in time would therefore be:
= 150 / 15
= 10 hours
As City B is East, it would be ahead in time. Time is therefore:
= 6 + 10
= 1600
= 4 pm
In conclusion, the time in City B would be 4 pm.
