· Nita heard the sound of lightning after 4 seconds of seeing it. What
was the distance of the lightning
from her?
(The velocity of sound in air is 340
m/s?)
​

1360 m

Explanation: Suppose Nita is stood in open ground and she heard the lightning sound after 4 seconds of seeing it.

Given that,

Velocity of sound in air = 340 m/s

Time required = 4 seconds

To find: Distance between Nita and that Lightning

So,

Velocity = Distance / Time

340 m/s = Distance / 4 seconds

Distance = 340 * 4

Distance = 1360 meters

Therefore, the distance of Lightning from Nita is 1360 meters.

The correct answer is option (C) "The next location would likely be in Pennsylvania because it is close to New York".

Explanation:

One of the most common tips for business growth is to look for territories where a high demand of the product is required, but also to territories where the risk of failure could be minimum. A New York-based business likely would look to expand to Pennsylvania, a large city at which the demand of their products could be justified, and a city that is relatively close to New York (170 miles) which facilitates the operation logistics.
