Question

At the start of a hike, a hiker was at an elevation of -50 feet (where O represents sea level). The hiker climbs at a rate of 15 feet per minute.Which inequality represents t, the number of minutes after the start of the hike, when the hiker's elevation was higher than 5 feet above sea level.Please see attached photo for options.

Answer 1

Answer:

The inequality is:

-50 + 15t > 5

The correct option is D

Step-by-step explanation:

The hiker was at -50 ft at the start.

Given that t represents the number of minutes after the start of the hike, since the hiker climbs at a rate of 15 ft per minute, we have:

-50 + 15t

This is said to be higher than 5 feet above sea level, that is;

-50 + 15t > 5
