We can infer and logically deduce that airplane’s ground speed is equal to 658.94 kph.
Given the following data:
Speed can be defined as the distance covered by an object per unit of time. Thus, speed can be measured in kilometer per hour (kph).
Mathematically, speed can be calculated by using this formula;
Speed = distance/time
In order to calculate the airplane’s ground speed, we would apply the law of cosine:
C² = A² + D² - 2(A)(D)cosθ
Substituting the given parameters into the formula, we have;
C² = 700² + 60² - 2(700)(60)cos45
C² = 434,203.03
C = √434,203.03
C = 658.94 kph.
In conclusion, we can infer and logically deduce that airplane’s ground speed is equal to 658.94 kph.
