Question

Each competitor starts from the bucket, picks up the nearest potato, runs back with it, drops it in the bucket, runs back to pick the next potato, runs to the bucket and drop it in, and continues in the same way until all the potatoes are in the bucket. What is the total distance the competitor has to run? ( Arithmetic Progrssion )

Answer 1

I think it............5

Answer 2

Distance covered by the competitor first

S(10) = 10/2[10 + 64]

= 5 × 74

= 370 m
