Let +d%5B1%5D+ = distance in km from Boston to Indianapolis
Let +d%5B2%5D+ = distance in km from SF to Indianapolis
The planes are heading in a straight line towards
each other, since SW is the opposite direction from NE
Plane from Boston:
+d%5B1%5D+=+150%2A8+
Plane from SF:
+d%5B2%5D+=+180%2A8+
---------------
+d%5B1%5D+=+1200+ km
+d%5B2%5D+=+1440+ km
+d%5B1%5D+%2B+d%5B2%5D+=+2640+ km
