An aerospace engineer is writing a Python program to calculate the average fuel consumption rate across three test runs of a prototype engine. Their initial draft of the script is shown below.
x = input("Enter fuel consumed in run 1 (litres): ")
y = input("Enter fuel consumed in run 2 (litres): ")
z = input("Enter fuel consumed in run 3 (litres): ")
f = (x + y + z) / 3
print("Average consumption is: " + f)
Give two ways that the maintainability of this program could be improved.
