Answer 1

Answer:

speed=63 km/h

Step-by-step explanation:

Let the distance traveled in North be x

height of the Bird from the ground is 2000m=2 km

Now Tan30= x/2

x=2* Tan30

Let the distance traveled in South be y

Now Tan45=y/2

y=2* Tan 45

Tan 30=1/root3 =1/1.73=0.578

Tan 45=1

Total distance travelled d=x+y=2*0.578 +2=1.15+2=3.15km

time 3 minutes= 3/60 hrs=0.05 hrs

speed=distance/time=3.15/0.05 km/hr=63 km/hr
