Program 1:

*2.17 (Science: wind-chill temperature) How cold is it outside? The temperature alone is not enough to provide the answer. Other factors including wind speed, relative humidity, and sunshine play important roles in determining coldness outside. In 2001, the National Weather Service (NWS) implemented the new wind-chill temperature to measure the coldness using temperature and wind speed.

The formula is

where t a is the outside temperature measured in degrees Fahrenheit and v is the speed measured in miles per hour. t w c is the wind-chill temperature. The formula cannot be used for wind speeds below 2 mph or temperatures below 58 F or above 41F. Write a program that prompts the user to enter a temperature between 58 F and 41F and a wind speed greater than or equal to 2 and displays the wind-chill temperature. Use Math.pow(a, b) to compute v 0.16 .

CLASS NAME: Your program class should be called WindChillTemperature

Here is a sample run:

Enter the temperature in Fahrenheit between -58F and 41F: 5.3

Enter the wind speed (>=2) in miles per hour: 6

The wind chill index is -5.56707

Program 2:

*2.23 (Cost of driving) Write a program that prompts the user to enter the distance to drive, the fuel efficiency of the car in miles per gallon, and the price per gallon, and displays the cost of the trip.

CLASS NAME: Your program class should be called CostOfDriving

Here is a sample run:

Enter the driving distance: 900.5

Enter miles per gallon: 25.5

Enter price per gallon: 3.55

The cost of driving is $125.36
