Task
1. Create a program that displays how long it will take the Shuttle to get to Mars.
2. Create a program that displays how long it will take the Shuttle to get to the Moon.
TIP:
Declare and assign a variable for each item in the list
Use the Console to check the output of each type of variable
Information
Name of the space shuttle: Determination
Shuttle Speed (mph): 17,500
Distance to Mars (km): 225,000,000
Distance to the Moon (km): 384,400
Miles per kilometer: 0.621
Solution
Determine how many days it will take to reach Mars
mars will take
Determine how many days it will take to reach the Moon
moon will take
