Question 972065: A plane is heading north-west at 480km/h and is in contact with another plane which leaves the same airport at the same time and heads north-east at 400km/h. How far apart are the planes (to the nearest km) after 90 minutes? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! A plane is heading north-west at 480km/h and is in contact with another plane which leaves the same airport at the same time and heads north-east at 400km/h.
How far apart are the planes (to the nearest km) after 90 minutes?
:
Change 90 min to 1.5 hrs
Find the distance each traveled in that time
480 * 1.5 = 720 km
400 * 1.5 = 600 km
The angle between the paths of the two aircraft is 90 degrees, so we can use:
a^2 + b^2 = c^2, where
a = 720
b = 600
c = distance between the two aircraft after 90 min
therefore:
c =
c = 937 km
