The bird is flying at 5m/s, so
1 sec = 5 m
It flies for 3 mins
3 mins = 3 x 6sec
3 mins = 180 sec
The bird flies for 180 seconds
1 sec = 5 m
180sec = 5 x 180 = 900m
The bird flew 900m in 3 mins (Answer C)
Answer:
X=19m
Step-by-step explanation:
A=LxW
W=A/L=225/25=9m
Rope used =perimeter
4(x-2)=2L+2W
4x-8=2x9+2x25
4x=68+8
X=76/4=19m
Use Pythagoras theorem that is ( h^2= p^2+b^2 ) but it depends what sort of a triangle is it
