It took him 2.6 hours to reach the top
Data;
- Uphill = 6km
- Downhill = 4km
- Total time taken = 8 hours
<h3>Speed</h3>
Let us calculate the speed during uphill and downhill
Since the time it took them to descend is twice the time it took them to ascend,
- Let x represent the time taken to ascend
![x + 2x = 8 hours\\3x = 8\\x = \frac{8}{3} \\x = 2.6 hours](https://tex.z-dn.net/?f=x%20%2B%202x%20%3D%208%20hours%5C%5C3x%20%3D%208%5C%5Cx%20%3D%20%5Cfrac%7B8%7D%7B3%7D%20%5C%5Cx%20%3D%202.6%20hours)
From the calculation above, it took him 2.6 hours to reach the top.

Answer:
1. 52 degrees 2. D
Step-by-step explanation:
1. The interior angles of a triangle add up to 180, so you can do 180 - 36 - 92 to find the third angle.
180 - 36 - 92 = 52 degrees
2. the angle XYZ has to equal the sum of the angles WXY and XWY. This means that 115 = 45 + XWY
115 - 45 = 72
XWY = D. 70 degrees
