Here are the essential concepts you must grasp in order to answer the question correctly.
Distance, Speed, and Time Relationship
The relationship between distance, speed, and time is fundamental in solving motion problems. It is expressed by the formula: distance = speed × time. Understanding how to manipulate this formula allows one to calculate any of the three variables when the other two are known.

Relative Motion
Relative motion involves analyzing the movement of two objects in relation to each other. In this problem, the plane and the car are moving towards a common point (the airport), and their speeds and departure times must be considered to determine the speed of the plane relative to the car's journey.

Unit Conversion
Unit conversion is crucial when dealing with different units of measurement, such as kilometers and hours. In this problem, converting time from minutes to hours is necessary to ensure that speed is calculated consistently in kilometers per hour, which is the standard unit for speed in this context.
