Final answer:
Here's a sample code in Python:
```python
# Prompt the user for input
capacity = float(input("Enter the capacity of your gas tank in gallons: "))
gauge_indication = float(input("Enter the gas gauge indication in percent: "))
miles_per_gallon = float(input("Enter the miles per gallon your car usually gets: "))
# Calculate the estimated distance
estimated_distance = (capacity * gauge_indication / 100) * miles_per_gallon
# Check if gas is needed
if estimated_distance < 200:
print("Get Gas. Estimated distance: ", estimated_distance, " miles")
else:
print("Safe to Proceed. Estimated distance: ", estimated_distance, " miles")
```
Step-by-step explanation:
Here's an example program using if statements to help drivers decide if they need gas:
1. Start by prompting the user to enter the capacity of their gas tank in gallons, the gas gauge indication in percent, and the miles per gallon their car usually gets.
2. Store the input values in appropriate variables.
3. Calculate the estimated distance the car can travel before running out of gas by multiplying the capacity of the gas tank by the gas gauge indication (converted to a decimal) and then dividing it by the miles per gallon.
4. Use an if statement to check if the estimated distance is less than 200 miles.
- - If the estimated distance is less than 200 miles, output "Get Gas" and the estimated distance.
- - If the estimated distance is greater than or equal to 200 miles, output "Safe to Proceed" and the estimated distance.
By running this program, the user will be able to determine whether they need to get gas or if it's safe to proceed based on their gas tank capacity, gas gauge indication, and miles per gallon their car usually gets. The program will also display the estimated distance the car should be able to drive before running out of gas.
