timama [110]

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

From the calculation above, it took him 2.6 hours to reach the top.
