The inequalities are:
1. \( h \geq 58 \) inches for the roller coaster height requirement.
2. \( s \geq 160 \) mph for the train's cruising speed.
Solución
1. Let h represent a visitor's height in inches. Since a visitor must be at least 58 inches tall, the inequality is:
h ≥ 58.
2. Let s represent the train's cruising speed in miles per hour. Since the cruising speed will be no less than 160 mph, the inequality is:
s ≥ 160.

To represent the height restriction for the roller coaster, you can write the inequality \( h \geq 58 \). This means that the height \( h \) must be greater than or equal to 58 inches for the visitor to be able to ride. For the bullet train's cruising speed, the inequality can be expressed as \( s \geq 160 \). This indicates that the speed \( s \) must be at least 160 miles per hour for the train to be considered in operation.
