Is that "k" as in "one thousand" as often used in the USA, or is it actually "km" (kilometres)?
150,000 kilometres is about 93 thousand miles. That is very high as an annual mileage for a domestic car (12,000 miles quoted in the UK on average, possibly 20,000 miles in some parts of Europe, probably a bit higher in the USA). Even for a commercial vehicle 93,000 miles per year seems high or reasonable.
Are you in fact asking about mileage in the overall working life of commercial vehicles? Your question does not make that clear.
