The difference in time between two longitudes is approximately
15 hours
4 hours
40 minutes
4 minutes
Correct answer is D
The Earth is divided into 360 degrees of longitude, so every degree of longitude is equal to 4 minutes of time. This is because there are 24 hours in a day and 360 divided by 24 is 15. Therefore, the difference in time between two longitudes is approximately 4 minutes. The other options are incorrect.

14^0C
66^0C
26^0C
(\12^0C\)
Correct answer is A
Lapse rate is simply described as 0.65°C per 100m of ascent or 6.5ºC per 1000m of ascent. Therefore 4000m of ascent= 6.5ºC x 4000m/1000m=26.0ºC Then, the temperature around the aeroplane is = 40ºC - 26ºC = 14°C
