It should me the number 32
The distance between Earth and the moon is 3.8 x 10^3 Kilometers. The time taken to travel this distance was 2.1 x 10^3 Minutes.
The formula to calculate speed is Speed = distance/time.
So, the speed of Luna I was 3.6 x 10^3 / 2.1 x 10^3 Kilometers/Mintues.
Step-by-step explanation:
a) The total cost C is given by
b) If the total cost is $400, then we can solve for the number of hours as
Solving for n, we get
I’m not sure if this was what you wanted but I used an app to calculate it.
