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

### Instruction:
Ralph is a member of the cross-country relay team. There are four other members on the team who run 3 km to complete their part of the race. Ralph runs twice as much as any member on his team to complete his part of the race. How long is the race?

### Response:
 Timu inapaswa kukimbia jumla ya km 20 kwa sababu 4 x 5 = <<4*5=20>>20.
Ralph hukimbia 4 x 3 = <<4*3=12>>12 km.
Mbio ni urefu wa km 18 kwa sababu 12 + 6 = <<12+6=18>>18.
