The inequality is:
-50 + 15t > 5
The correct option is D
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
