Answer
<u>A rapid improvement in standard of living can mean rapid economic growth with increased population in towns resulting to damaged environment in form of pollution.</u>
Explanation
When the standard of living is associated with rapid growth of the economy, a common scenario is migration of people to urban areas to work and operate businesses. The urban areas will experience increased populations with inadequate housing. The environment will be suppressed because more forests will be cleared to give out spaces for new housing projects. In addition to that, the pollution levels will increase because more wastes will be generated.
The number of degrees of longitude that separate New York City and Reno, Nevada is 120 – 75 = 45 degrees of longitude. The time difference can be calculated by dividing it by 15 degrees because for every 15 degrees there is 1 hr difference. 45 / 15 = 3 hr difference
