If there are approximately 1.8 million cars in Vancouver and if each car travels an average of 17,500 kilometres in a year, how much gasoline is used per year for all of the cars, assuming an average gas mileage of 40 miles per gallon? Provide your answer in litres in scientific notation to 2 decimal places. Show all your work.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
