The speed of light is exactly e = 299792458 m •sl. (Also written 299, 792, 458 m · s"! or 2.99792458 × 10°m · s1. This is exact because it is the definition of the metre.) It takes light 8.3 minutes to get from the sun to the earth. Assuming that the earth's orbit is exactly circular (an approximation) and that its speed is constant, and using the data in this question, calculate the speed of the earth in its orbit around the sun in km · hr. Practise writing your conversions clearly using the 'multiply by 1' technique. Speed of the earth = _km per hour. Write your answer in standard (not scientific) notation, i.e. without using exponents, and without using commas. However, remember to use the correct number of significant figures. (Hint: which is the least precise of the given data?) Do not include units.
