Question

47)an aeroplane flies along the sides of an equilateral triangle with speed of 300 km/hr, 200 km/hr,240 km/hr. the average speed of the plane while flying around the triangle is:

Answer 1

First speed = 300 km/hr
Second Speed = 200km/hr
Third speed = 240km/hr
Average speed = (First Speed + Second Speed + Third Speed) / 3
Average Speed = (300+200+240)/3
Average Speed= 740/3
Average Speed= 246.66 km/hr
