Since java.util.PriorityQueue doesn't use the Cloneable interface, I think it's safe to say that Serializable interfaces are implemented in all instances.

The Fast as Light Shipping company charges the following rates. Weight of the item being sent Rate per 100 Miles shipped 2kg or
Pie

Answer:

weight = float(input("Enter the weight of the package: "))

distance = float(input("Enter the distance to be sent: "))

weight_charge = 0

if weight <= 2:

   weight_charge = 0.25

elif 2 < weight <= 10:

   weight_charge = 0.3

elif 10 < weight <= 20:

   weight_charge = 0.45

elif 20 < weight <= 50:

   weight_charge = 1.75

if int(distance / 100) == distance / 100:

  d = int(distance / 100)

else:

   d = int(distance / 100) + 1

   

total_charge = d * weight_charge

print("The charge is $", total_charge)

Explanation:

*The code is in Python.

Ask the user to enter the weight and distance

Check the weight to calculate the weight_cost for 100 miles. If it is smaller than or equal to 2, set the weight_charge as 0.25. If it is greater than 2 and smaller than or equal to 10, set the weight_charge as 0.3. If it is greater than 10 and smaller than or equal to 20, set the weight_charge as 0.45. If it is greater than 20 and smaller than or equal to 50, set the weight_charge as 1.75

Since those charges are per 100 miles, you need to consider the distance to find the total_charge. If the int(distance / 100) is equal to (distance / 100), you set the d as int(distance / 100). Otherwise, you set the d as int(distance / 100) + 1. For example, if the distance is 400 miles, you need to multiply the weight_charge by 4, int(400/100) = 4. However, if the distance is 410, you get the int(400/100) = 4, and then add 1 to the d for the extra 10 miles.

Calculate the total_charge, multiply d by weight_charge

Print the total_charge
