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

### Instruction:
Jeff is collecting matchbox cars. He has twice as many cars as trucks. He has 60 total vehicles. How many trucks does he have?

### Response:
 Idadi ya malori + 2(idadi ya malori) = 60
Hivyo 3(idadi ya malori) = 60
Idadi ya malori = 20 kwa kuwa 60 / 3 = <<60/3=20>>20
