first the person goes to (2,2) from (1,1) +141 then (3,2) +100 so why not 241?

(0, 0) -> (1, 1) = sqrt(2) * 100
(1, 1) -> (2, 1) = 100
(2, 1) -> (3, 2) = sqrt(2) * 100

Total: 382.842712475 ~ 383

Then shouldnt the problem wording be stated as rounding the solution to the nearest integer? If I just round 382.84 to its integer value, it would be 382.
