The Helicopter flies along a Square field @ 100, 200, 300 and 400 km/hours respectively. Then find the Average speed of the helicopter during the whole journey?
Concept of Average Speed: LCM of 100, 200, 300 and 400 = 1200 Now, Average Speed = Total distance travelled/Total time taken = (1200 ×4)/(1200/100+1200/200+1200/300+1200/400) = (1200 ×4)/25= 192 kmph
