Hello,
Question:
Jack popped some popcorn, but 3 of the 150 kernels did not pop.
Determine which popcorn snacks below has the same ratio of unpopped to total kernels as Jack's popcorn.
We Know:
3 out of 150 did not pop
Solution:
3/150 = 3 to 150
Find ratios similar to this one,
4/200
2/100
1/50
So now we know for every kernel that dosent pop there are 50 that did.
Answers:

1 unpopped out of 50 kernels
Answer:
0.5hrs
Step-by-step explanation:
Let the speed downhill be ,
Speed uphill is . We are told than speed uphill is the speed on flat ground. Therefore the speed on level ground will be .
From this info, we can obtain the actual speed, on level ground as:
speed, distance and time have the relation so to obtain time to cover 45miles:
Hence it takes 0.5hrs to cover 45miles on flat ground.
