Answer:
1st portion
Step-by-step explanation:
Time taken for the 1st part of the hike = 10 minutes
Change in elevation in 1st part = - 200 feet
The negative sign indicates that the elevation is decreasing. So this means, elevation of Nola decreased by 200 feet in 10 minutes during this part.
We need to find out the rate i.e. the speed of her walk or hike. Since, speed is the ratio of distance to time, in this case it would be:
Using the values, we get:
feet per minute
This means during the 1st part her rate of walk was 20 feet per minute down the hill.
Time taken for the 2nd part of the hike = 20 minutes
Change in elevation in 2nd part = - 300 feet
Using the same formula we used above, we get:
feet per minute
This means during the 2nd part her rate of walk was 15 feet per minute down the hill.
Thus, Nola hiked down faster in the 1st portion of the hike.
