A

118.5 km

B

204.8 km

C

196.2 km

D

201.6 km

E

250.4 km

Show Answer

Correct Answer :

Option D

201.6 km

Solution :

The correct answer is 201.6 km.

Let's solve the problem step-by-step by calculating the speed of each vehicle/drone.

Step 1: Calculate the speed of the cargo carrier
Distance covered by cargo carrier = 240 km
Time taken = 5 hours

Using the speed formula, Speed=DistanceTime:

Speed of cargo carrier=2405=48 km/h

Step 2: Calculate the speed of the Hawk drone
The speed of the Hawk drone is 32 times the speed of the cargo carrier.

Speed of Hawk drone=32×48

Speed of Hawk drone=3×24=72 km/h

Step 3: Calculate the speed of the Falcon drone
The average speed of the Falcon drone is 75 times the average speed of the Hawk drone.

Speed of Falcon drone=75×72

Speed of Falcon drone=5045=100.8 km/h

Step 4: Calculate the distance covered by the Falcon drone in 2 hours
Using the distance formula, Distance=Speed×Time:

Distance=100.8×2=201.6 km

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