Question

write inequalities to represent the situations below.
to be eligible for the senior admission rate, a visitor must not be less than 55 years old.
use y to represent the age (in years) of a visitor who gets the senior rate.
the cruising speed of the bullet train will be at least 150 miles per hour.
use s to represent the trains cruising speed (in miles per hour).

Explanation:

Step1: Analyze the first situation

The visitor must not be less than 55 years old, which means the age \( y \) is greater than or equal to 55. So the inequality is \( y \geq 55 \).

Step2: Analyze the second situation

The cruising speed \( s \) is at least 150 miles per hour, which means \( s \) is greater than or equal to 150. So the inequality is \( s \geq 150 \).

Answer:

For the first situation: \( y \geq 55 \)
For the second situation: \( s \geq 150 \)
