Answer:
45 km/hr
Explanation:
total distance = 90
Increased speed = x+15
90/x - 90/x+15=1/2
90(1/x - 1/x+15)=1/2
90(x+15-x/x^2+15x)=1/2
equation is:
x^2+15x-2700=0
x^2+60x-45x-2700=0
x(x+60)-45(x+60)=0
(x+60)(x-45)=0
x= -60, x=45
reject the negative value = -60
usual speed=45 km/ hr
By the late 1930's and with the beginning of World War II, the American political spectrum was divided over the United States's role in Europe.
The Fight For Freedom Committee was against neutrality wanted to strong action against countries creating trouble in Europe.
On the other hand was the group

Explanation:
Answer is :
<h3>6.778 meters. </h3><h2>Explanation:</h2>
y = u t + 1/2 at²
6 m = u sinθ + 1/2 at²
6 m = (12) sin 30°t + 1/2 (9.81)t²
4.905 t² + 6 t -6 = 0
By solving, t = 0.6522 s.
The horizontal distance :
x = u cosθ t
= (12) cos 30° (0.6522)
<h2>= 6.778 meters.</h2>
