An aircraft flies from P (40°N, 38°E) to Q (40°N, 22°10) if thereafter flies to get another point R (28°N, 22°W). calculate: a) The distance between Q and R along their parallel of latitudes.

b) The average speed of the aircraft for the whole journey if it takes 12 hours. (Take π = 3.142)​

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
