Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Surfers enjoy going to the Rip Curl Myrtle Beach Surf Festival. There were 1500 surfers at the Festival on the first day, 600 more surfers on the second day than the first day, and 2/5 as many surfers on the third day as the first day. What is the average number of surfers at the Festival for the three days?

### Response:
 Ikiwa idadi ya wavuvi siku ya pili ilikuwa wavuvi 600 zaidi ya siku ya kwanza, basi kulikuwa na wavuvi 1500 + 600 = <<1500+600=2100>>2100 siku ya pili.
Siku ya tatu, idadi ya wavuvi ilikuwa 2/5 ya idadi ya siku ya kwanza, jumla ya wavuvi 2/5 * 1500 = <<2/5*1500=600>>600.
Jumla ya wavuvi kwenye Tamasha kwa siku tatu ni 1500 + 2100 + 600 = <<1500+2100+600=4200>>4200 wavuvi.
Wavuvi kwa wastani kwenye Tamasha la Kusurfa la Myrtle Beach kwa siku tatu ni 4200/3 = <<4200/3=1400>>1400 wavuvi.
