Answer 1

Answer:

370 m

here you go your answer but u have to mark my ans as brainliest

Step-by-step explanation:

Distance travelled by the participant in order to pick up the first ball and drop it in the bucket= 4 + 4 = 8 m

Distance travelled by the participant to pick up the second ball and drop it in basket = 4 + 4 + 4 + 4 = 16 m

Similarly, distance travelled by competitor to pick up third, fourth, fifth, sixth, seventh, and eighth balls are 24 m, 32 m, 40 m, 48 m, 56 m, 64 m

 

 

a = 8 m

common difference  = d = 8m

 

 

 

So, each participant has to cover a distance of 288 m in order to complete the race
