The distance is the same for each flyer
d%5B1%5D+=+d%5B2%5D
r%5B1%5D%2At%5B1%5D+=+r%5B2%5D%2At%5B2%5D
107.4t+=+217.1%28t+-+16.95%29
107.4t+=+217.1t+-+3679.85
109.7t+=+3679.85
t+=+33.54hrs
t+-+16.95+=+16.59hrs
Lindbergh's distance was
r%5B1%5D%2At%5B1%5D+=+107.4%2A33.54
r%5B1%5D%2At%5B1%5D+=+3602mi
Hugh's distance should be the same
r%5B2%5D%2At%5B2%5D+=+217.1%2A16.59
r%5B2%5D%2At%5B2%5D+=+3602mi
