*urgent *the total number of vertical feet that a climber has traveled varies directly with the number of hours she has been climbing. the constant proportionality is 600.

The answer is:

a) 300

b) 600

c)

d)

e) 2400

The explanation is shown below:

1. You have that the total number of vertical feet that a climber has traveled (which you can call ), varies directly with the number of hours she has been climbing (which you can call ), and the constant of proportionality is 600 ().

2. Keeping this on mind you can express it as following:

3. Now, substitute the values given in the table and solve for to calculate the number of feet or solve for to calculate the time in hours:

a)

b)

c)

d)

e)
