Question

Two aircraft, A and B, leave an airport at the same time. A flies on a course of 81 degrees at 652 km/h, and B flies on a course of 272 degrees at 546 km/h. Calculate their distance apart after 25 minutes to the nearest kilometer. Show ALL your work.

Answer 1

the angle between the two courses is ... 272 - 81 = 191
... 360 - 191 = 169 ... this is the included angle

find the distances along the two courses ... distance = rate * time

you now have two sides of an obtuse triangle and the angle between them

use the Law of Cosines to find the 3rd side (the distance between the aircraft)

Answer 2

Just asking, what would the answer be.
This is so that I can check my work to see if I did it right. This would be very very helpful!!!!!!!!!

Thanks

Answer 3

haven't solved it ... post a number and I'll be happy to check it

Answer 4

My answer was 497km. It would be great if you could check that for me

Answer 5

looks good
