Question
An Aeroplane flies along a Square field @ 50, 100, 200
and 400 km/hours respectively. Then find the Average speed of the aeroplane during the whole journey?Solution
Concept of Average Speed: LCM of 50, 100, 200 and 400 = 400 Now,Let side = LCM of 50, 100, 200 and 400 = 400 Now, Average Speed =total distance/ total time= (400 ×4)/(400/50+400/100+400/200+400/400) = (400 ×4)/15= 106.67 kmph
