If the chance you will be able to stop suddenly at a stop sign in four inches of snow varies inversely with the speed you are going, the relationship can be represented by the values, if x = 20 miles per hour and y = 80% chance of stopping, then what is y if x is 50 miles per hour?

Question

solomonzelman · Answer

80%=20k   k=?

when you find k, plug it into

? % = 50 k



See what I am doing?

anonymous · Answer

Yes I do ^.^ You divide the first equation by 20, that will equal k. Then yeah, plug the k in, right?

anonymous · Answer

Okay so it would turn out to be ?% = 50 (4), which then equals 200?

Ooop, sorry. I misread the q.

20 miles per hour

80% chance the car will stop....

those 2 vary inversely.

I would say yk=x

so 80%k=20

then find k, and plug it into 

?% k = 50





I am not sure though.

Yeah, another student wrote the problem, sorry about the confusion :/
Okay, so k would equal 0.25, sooo 0.25k = 50? I am so confused haha
