Answer:
Part a =
The distance between Earth and the moon is 3.8 x 10^5 kilometers. The time taken to travel this distance was 2.16 x 10^3 minutes.
The formula to calculate speed is speed = distance/time.
So, the speed of Luna I was 3.8 x 10^5/2.16 x 10^3 kilometers/meters.
Part b =
The expression from part A is 3.8 x 10^5/2.16 x 10^3 kilometers/meters. Break the expression into the product of two fractions, one fraction for the first factors and the other for the powers of 10.
3.8/2.16 x 10^5/10^3
Part c =
3.8/2.16 x 10^5/10^3
Using division, the value of the first fraction is 3.8/2.16 = 1.759 = 1.76.
Using the properties of exponents, the value of the second fraction is 10^5/10^3 = 10^5 x 10^-3 = 10^ 5 - 3 = 10^2.
3.8/2.16 x 10^5.10^3 = 1.76 x 10^2
Part d =
The value 1.76 x 10^2 is written in scientific notation. So, the average speed of Luna I was 1.76 x 10^2 kilometers/minute.
