Resultant displacement between the base camp and the cave will be 7.211 km
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Her resultant displacement can be calculated using Pythagoras theorem

Answer:

Explanation:
The torque applied on an object can be calculated by the following formula:

where,
T = Torque
F = Applied Force
r = radius of the wheel
For car wheel:

For truck wheel:

Dividing both:

for the same force applied on both wheels:

where,
rt = radius of the truck steering wheel = 0.25 m
rc = radius of the car steering wheel = 0.19 m
Therefore,
