It is a long, downhill walk (12.6 km) from the youngest rocks (270 Ma) at the rim of the canyon to the oldest rocks (2,000 Ma) at the river. Using this information, estimate how far back in time you would go with each meter along the trail. a. 158,730 yr/m
b. 1,373 yr/m
c. 1,587 yr/m
d. 137,302 yr/m

137,302 yr/m

Explanation:

Given the information in the question, we can denote that:

Distance= 12.6 km = 12600 meters

The difference between the youngest and the oldest rock is given as:

= 2000 Ma - 270 Ma

= 1730 Ma

Therefore, the number of years that one would go with each meter along the trail will be:

= (1730 × 10^6) / 12600

= 1730000000 / 12600

= 137,302 yr/m
