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

### Instruction:
A passenger train transports passengers between two stations located in two separate cities. On a particular day, the train carried 100 passengers from one station to the other one way, and on the return trip carried 60 passengers. If the train made three more round trips that day, taking the same number of people as the first trip in each trip, calculate the total number of passengers transported between both stations?

### Response:
 Idadi jumla ya watu waliokwenda katika safari ya kwanza ni 100 watu njia moja + 60 watu njia ya kurudi = <<100+60=160>>160 watu.
Jumla, treni ilisafirisha watu 160 * 3 safari = <<160*3=480>>480 watu katika safari tatu.
Ikiwa ilifanya safari tatu ikisafirisha watu 160 kila safari, idadi jumla ya watu waliokwenda katika safari zote ni 160*4 = <<160*4=640>>640 watu.
