Solve the following word problem.
The average speed of a Falcon drone is times the average speed of a Hawk drone. A cargo carrier covers 240 km in 5 hours. If the speed of the Hawk drone is times the speed of the cargo carrier, then how much distance will the Falcon drone cover in 2 hours.
Correct Answer :
201.6 km
Solution :
The correct answer is 201.6 km.
We are given three flying objects — a Falcon drone, a Hawk drone, and a cargo carrier — with relationships between their speeds. Let's work through this step by step.
Step 1: Find the speed of the cargo carrier.
The cargo carrier covers 240 km in 5 hours. Using the basic formula:
So, the speed of the cargo carrier is 48 km/h.
Step 2: Find the speed of the Hawk drone.
The Hawk drone's speed is times the speed of the cargo carrier:
So, the speed of the Hawk drone is 72 km/h.
Step 3: Find the speed of the Falcon drone.
The Falcon drone's speed is times the speed of the Hawk drone:
So, the speed of the Falcon drone is 100.8 km/h.
Step 4: Calculate the distance the Falcon drone covers in 2 hours.
Using the distance formula:
Therefore, the Falcon drone will cover 201.6 km in 2 hours.
