There is a proportional relationship between your distance from a thunderstorm and the time from when you see the lightning and hear the thunder. If there are 9 seconds between the lightning and thunder, the storm is about 3 kilometers away. If you double the amount of time between the thunder and the lightning how far away is the storm?
3KM=9sec(T)x R 0.33=R d=18sec x 0.33 5.94=d
It must be 6km away.
A store sells 3 ears of corn for $1. They round prices to the nearest cent as shown in the table. Tell whether you would describe the relationship between cost and the number of ears of corn as a proportional relationship. justify your answer
To find the distance of the storm when there are 18 seconds between the lightning and thunder, you can use the proportional relationship between distance and time.
Let's set up the proportion:
Distance / Time = Constant
Using the values we have, we can write:
3 km / 9 sec = X km / 18 sec
To solve for X (the distance when there are 18 seconds between lightning and thunder), we can cross multiply and solve for X:
9 sec * X km = 3 km * 18 sec
9X = 54
Dividing both sides by 9:
X = 6
Therefore, when there are 18 seconds between lightning and thunder, the storm is approximately 6 kilometers away.
