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 1083-957= 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)

**Reiny**, Thursday, July 26, 2012 at 12:24pmI 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

**INDIANA**, Thursday, July 26, 2012 at 12:48pmhow 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

**Reiny**, Thursday, July 26, 2012 at 1:04pmfrom 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.
