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

### Instruction:
William washes cars as a side job. He typically spends 4 minutes washing a car’s windows, 7 minutes washing the car body, 4 minutes cleaning the tires, and 9 minutes waxing the car. This morning he washed 2 normal cars and one big SUV, which took twice as long as a normal car. How many minutes did William spend washing all the vehicles?

### Response:
 William anafua gari la kawaida kwa dakika 4 + 7 + 4 + 9 = <<4+7+4+9=24>>24.
William alifua magari 2 ya kawaida, hivyo alitumia dakika 24 * 2 = <<24*2=48>>48 kufua magari ya kawaida.
Alifua SUV moja, ambayo ilichukua dakika 24 * 2 = <<24*2=48>>48 kufua.
Hivyo, William alitumia dakika 48 + 48 = <<48+48=96>>96 kufua magari yote.
