a) 6:00 am b) 6:40am c)7:40 d)7:00 e)8:00

Latitudianal difference=(10+70)=80
So, time difference=80X4=320mins=5 hrs 20 mins
Since the place is located towards west
Therefore local time of that place during take off=8:40 p.m.
So, local time during landing=8:40p.m.+10hrs=6:40a.m.

Answer / kris
Latitude change = (10 + 70 ) = 80 degrees
1 degree change corresponds to 4 min difference
So total time difference = 80 * 4 = 320 min
= 5 hrs 20 mins
In going from east to west , time decreases
Local time = 2 am + 10 - 5hr 20 min
= 6.40 am

Answer / archana virmani
If west to east add time else subtract time so
the longitude difference is (70-10)=60 deg
Every 1 deg longitude is equal to 4 mins....
the change in the angle = 4*60=240 min = 4 hrs
means while moving from east to west we have a loss of 4 hrs
i.e 10 hrs - 4 hrs = 6 hrs
thus we have 2am + 6 = 8am

Answer / neelay kumar
As we know that 1 deg =4 min.
and latitude change=(10+70)=80(That flight at 2 am making 10 deg with north and after 10 hrs ,it is making 70 deg with north.)
therefore,80 deg=(80*4)mins
=320 mins.
=5hrs 20 mins.
local time difference between source and destination place=5 hrs 20 mins
hence,after 10 hrs ,according to a person ,it should be 12 pm.
but local time at that place=12 pm-5 hrs 20 mins
=6 am 40 mins.

Answer / pankaj
The earth rotates by 360 degree in 24 hours
thus, in 1 hour it rotates by 15 degree
So, the time difference b/n the two places is 80/15 hour
= 5 hour & 20 min
So, at the take off, the time at the destination
=2am - 5 h & 20 min
=8:40 pm
After 10 hours the time will be, 6:40 am
ans (b)

Answer / naveen
The destination place is 80 degree west to the starting
place. Hence the time difference between these two places is
5 hour 20 min. (=24hr*80/360).
When the flight landed, the time at the starting place is 12
noon (2 AM + 10 hours).
Hence, the time at the destination place is 12 noon - 5:20
hours = 6: 40 AM

Answer / ganesh karki
Latitudianal difference=(10+70)=80
we know 1 deg=4 minute
time difference=80X4=320mins=5 hrs 20 mins
we know the place is located towards west
Therefore local time of that place during take off= (2am-5.20hrs) = 8:40 p.m.
So, local time during landing=8:40p.m.+10hrs
Ans =6:40a.m.
(this is wrong the longitude difference is (70-10)=60 deg)
cos we can't subtract longitude.

Answer / nataraj
Latitude 1=10E
Latitude 2=70W. Since its a sphere it has a total of 180degrees. So the latitudinal difference is
(180-70)+10=120 degrees and time difference will be 8hrs. After 10hrs time in starting place is 12noon then the time in destination will be 4am. Is this right?
Is This Answer Correct ? | 1 Yes | 6 No |
Answer / anand
70W -10E= 60
1 DEG = 4 MINS Hence for 60 deg 240 mins
= 4 hrs
Travelling east to west is time loss of 4 hrs from 10 hrs
= net travel = 6
started at 2 am means reaching at 8 am
