A jet pilot flies 100 km north to an airport, then 1400 km east to another airport, then finally 1000 km north to a third airport.

a) What is the total distance covered by the plane?
b) How far is the pilot from the original point of take

1 answer

(a) 100+1400+1000 = 2500 km
(b) Since he ends up 1100 N and 1400E,
d^2 = 1100^2 + 1400^2
