I am posting my question in two parts. can some one answer for me please.

Maps application.

The citizens of Hazard County have become aware of contamination in Mill Stream, a tributary of the Clearwater River. They are concerned that this change in the quality of the river water will affect the river's ecosystems.

You will be sampling water from Mill Stream and three of its tributaries to determine if any of them are the source of the contamination. If the source can be discovered, remediation may be possible so that the water quality can be improved before it enters the Clearwater River.

To begin to determine the source of the contaminant, you must collect samples from several sites along Mill Stream and each of its three tributaries. You will perform field tests on the samples you collect, and you will also collect further samples to be tested in a laboratory.

Before you set out to collect your samples, you should determine the distance you will travel and the easiest way to complete the route. Once you know the length of your route and how long it will take you to collect samples and perform field tests, you can determine the total time it will take you to complete the collection of samples from all 12 sites. You will begin at the campground near Maverick Plateau.

To complete your work, use the links on the left. These resources will help you

·         Identify items from map legends

·         Understand map scale

·         Read topographic maps

·         Calculate rate, distance, and time problems

·         Determine the distance between points

·         Calculate route distance

Part A - Reading topographic maps

Using what you know about topographic maps, identify the elevation of 6 of the 12 sites on the Plateau Map below. Review the information at the Reading Topographic Maps link if you need a refresher on how to read topographic maps.

Drag the appropriate labels to their respective targets.

Taking into consideration what you know about water quality and topographic maps, you will conduct field tests of the 12 sites. Use all your tools and expertise to determine the correct answers to the questions below. Review the map above again, or click the Plateau Map link, and note the scale at the bottom. Once you return and analyze your data, it can be viewed for each site on the map at the Plateau Map link. Click on each site to see the results and to help you determine where to focus in future testing. Review the Water Quality page for more information on water testing.Part B - Performing field tests

Drag the appropriate answers to their respective questions.

Now you will use your topographic knowledge to answer a few more questions that field geologists often think about. These skills are important for navigating terrain and assessing many types of hazards.

Part C - Calculating gradient: Spider Run

Gradient (or slope) is calculated as the change in elevation (feet) divided by the distance traveled (miles). Using the map at the Plateau Map link, what is the approximate gradient of the trail at Spider Run? Note the length of the trail runs from Site 4 to Site 5.

Choose from part(1,2,3,4)

1. 100 feet/mile

2. 140 feet/mile

3. 920 feet/mile

4. 280 feet/mile

Part D - Calculating gradient: Lye Run

Gradient (or slope) is calculated as the change in elevation (feet) divided by the distance traveled (miles). Using the map at the Plateau Map link, what is the approximate gradient of the stream at Lye Run? Assume the trail ends at the top of the stream bed (blue line).

Explanation / Answer

Part A:

Site 1: 890 feet

Site 2: 850 feet

Site 5: 924 feet

Site 6: 860 feet

Site 9: 960 feet

Site 10: 878 feet

Part B:

Answer 1: 3.2 miles

Answer 2: 260 feet

Part C: Answer 4 (920-780 feet/0.5 miles = 280 feet/mile)

Part D: Answer 3 (1020-760 feet/0.4 miles = 650 feet/mile approximately)
