Luna I made the 3.8 x 10^5 kilometers trip to the moon in 2.16 x 10^3 minutes.

Write an expression for the speed of Luna I in kilometers/minute. Represent this expression as a quotient of two numbers expressed in scientific notation.

Rewrite the expression you found in part A as the product of two fractions. The first fraction should be the first factors and the other fraction should be the powers of 10.

Estimate the value of the first fraction in part B to the hundredths place. Simplify the second fraction using the properties of exponents.

Is the value you found in part C represented in scientific notation? If not, convert the value to represent it in scientific notation. Also, write the average speed of Luna I in the most appropriate unit of measurement.
