Answer:

the correct answer is option B:

B) e=400×h

Explanation:

The distance [tex]\( e \)[/tex] descended by the hikers after [tex]\( h \)[/tex] hours can be expressed by multiplying the rate of descent (400 feet per hour) by the number of hours [tex]\( h \)[/tex] they've been descending.

So, the correct expression would be:

[tex]\[ e = 400 \times h \][/tex]

Therefore, the correct answer is option B:

[tex]\[ e = 400 \times h \][/tex]
