Correct Answer :

Option D

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:

Speed=DistanceTime=2405=48 km/h

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 32 times the speed of the cargo carrier:

Speed of Hawk=32×48=1442=72 km/h

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 75 times the speed of the Hawk drone:

Speed of Falcon=75×72=5045=100.8 km/h

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:

Distance=Speed×Time=100.8×2=201.6 km

Therefore, the Falcon drone will cover 201.6 km in 2 hours.
