an aircraft's reading shows
time 8:55 at distance travelled 957km
time 9:07 at distance travelled 1083
calculate distance travelled in km
calculate the average speed of aircraft in km/h
(for the 1st question 1083957= 126km)
(the second one should i add 1083+957km then divided it by both times minuses or the both times added to get the average speed)


I will assume you want the avg speed between 8:55 and 9:07. We cannot calculate the average speed for the whole trip since we don't know the starting time.
average speed = total distance/total time
= 126/(12/60) , time from 8:55 to 9:07 = 12 min = 12/60 hrs
= 630 km/h 
how did you get 12 min from 8:55 to 9:07?? and is the 1st answer that i have correct... because the link says otherwise

from 8:55 to 9:00 is 5 minutes
from 9:00 to 9:07 is 7 minutes, so .....
Your question "calculate distance travelled in km" is not clear
Do you want the total distance travelled, that would be 1083
between 8:55 and 9:07 it would be 126 km
Overall, a very poorly worded question. 
that is what was asked it never said total distance it said calculate distance traveled in km
