We need to make sure the units are the same. I will convert km to cm

3 km *1000m/1km * 100cm/1m =300000 cm

Now we can write the equation

P * 300000 = 30

Divide each side by 300000

P 300000/300000 = 30/300000

P =.0001

Changing this from decimal to percent

P = .0001*100 = .01 %

A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its r

frosja888 [35]

You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.

(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction

(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds
