Answer:
8
Step-by-step explanation:
sin theta = opposite side/ hypotenuse
sin 30 = 4/x
Multiply each side by x
x sin 30 = 4
Divide each side by sin 30
x sin 30 /sin 30 = 4 sin 30
x = 4 /sin 30
We know that sin 30 = 1/2
x = 4 / 1/2
x = 8
The answer is 8.4km/hr
(6+6+6+12+12)÷5=8.4
I don't know how to explain it it's as easy as 2+2 but as hard as explaining how to get 4 from 2+2
