This would make a good math question

That is a windspeed of 850 m/s
A typical airplane travels at about 250 m/s

a) If an airplane A leaves TLV at noon traveling west at 250m/s, and encounters headwinds of 850m/s. How fast does the airplane fly?
b) At what time will the airplane reach EWR?

Answers:
a) -600m/s
b) Quarter to never.
