Question

An aeroplane flies along sides of equilateral triangle with speeds 300km/hr,200km/hr,250km/hr . calculate its average speed

Answer 1

(300+200+250)/3=750/3=250km/hr

Answer 2

GIVEN; S1=300km/hr,S2=200km/hr,S3=250km/hr

TO FIND;
average speed(S)=?

SOLUTION;

Average speed(S)=(S1+S2+S3)÷3

S=(300+200+250)÷3

S=750÷3

S=250km/hr or S=250÷(5/18) m/s

S=(250×18)÷5

S=50×18

S=900m/s

THEREFORE,S=250km/hr Or 900m/s
