All right, as we set up this situation, we have two planes.
00:04
One is heading out at 3 pm, traveling at a bearing of south 70 degrees east.
00:13
So that's the direction this plane is heading.
00:16
It's averaging 450 miles per hour and travels for a time of three hours.
00:24
So we think three times 450.
00:29
That means this plane is going to travel 1 ,350 miles in that time frame.
00:36
The second plane leaves at five o 'clock, heading at a bearing of north 10 degrees west.
00:43
All right, that plane only travels for an hour because we're looking at 6 pm.
00:49
So this plane travels a total of 510 miles.
00:54
We are looking to find how far apart the planes are...
