Problem 2-1(c) Average Speed - Part 5 - C

Determine the average speed in metres per second. Express the final answer in scientific notation using the correct number of significant digits.
(C) The moon takes \(27.3\) days to complete one orbit around the earth. The average earth-moon distance is \(\mathrm{3.84 \times 10^5\; km.}\)


\(27.3 \; \text{days} \times 24 \frac{hr}{day} \times 3600 \frac{sec}{hr} = 2.359 \times 10^6 \; s\)

The speed is given by:

(A)   \(\text{speed} = \frac{\text{distance}}{\text{time}}\)

(B)   \(\text{speed} = \frac{\text{time}}{\text{distance}}\)

(C)   \(\text{speed} = \text{time} \times \text{distance}\)
