Hello there! Thank you for asking your question here at Brainly! I will be assisting you today with answering this problem, and will teach you how to handle it on your own in the future.
First, let's take a look at our problem.
"The speed of a ship is given by D3, where D is the distance the ship travels in 3 hours. If the ship travels 48 miles in 3 hours, what is the speed of the ship?"
To solve for this, we need to understand the formula for speed.
The formula for speed is:
Speed =
Now that we have our formula, let's define our variables.
So, we have our distance, 48 miles, and our time, 3 hours.
Let's plug in these numbers to the formula.
Speed =
Simplify the fraction to get the speed.
= 16.
Your final equation is:
Speed = 16.
Our final answer is 16 mph.
I hope this helps!

a. The lightbulb uses the energy of 960 W or 9.60 kW.
Step-by-step explanation:
Step 1:
To determine the energy used by the appliances we need to understand the equation
To determine the energy used, we multiply the power of the appliance with the amount of time it has been used for.
Step 2:
The lightbulb has a power of 60 W and is used for a period of 16 hours.
The energy used by the lightbulb W = 0.96 kW.
The toaster oven has a power of 1,500 W and is used for 0.75 hours.
The energy used by the toaster oven W = 1.125 kW.
