A rectangular park is 600 m long and 300 m wide. You walk diagonally across the park from corner to corner. How far do you walk, to the nearest meter?

840 meters

WRONG AGAIN

The bot can't even do a simple Pythagoras problem

d^2 = 600^2 + 300^2 = 450,000
d = √450,000
= 671 m , to the nearest metre
