Question

The average distance between the Sun and a certain planet is approximately $2.3\times {10}^{14}$ inches. Which of the following is closest to the average distance between the Sun and the planet, in kilometers? (1 kilometer is approximately $3.9\times {10}^4$ inches )

• A. $7.1\times {10}^8$
• B. $5.9\times {10}^9$
• C. $1.6\times {10}^{10}$
• D. $2.4\times {10}^{11}$
• E. $7.1\times {10}^{11}$

Answer 1

The correct option is B $5.9\times {10}^9$

The average distance in KM will be $\frac{2.3\times {10}^{14}}{3.9\times {10}^4}=0.59\times {10}^{10}=5.9\times {10}^{9}km$

So correct answer will be option B
