For the bullet train’s cruising speed, \( s \geq 140 \). For the runner’s qualifying time, \( t \leq 55 \).
Solución
For the bullet train’s cruising speed, let s represent the speed in miles per hour. “No less than 140” means the speed is at least 140, so the inequality is:
s ≥ 140
For the runner’s qualifying time, let t represent the time in minutes. “At most 55 minutes” means the time is no more than 55 minutes, so the inequality is:
t ≤ 55

The inequality representing the cruising speed of the bullet train can be written as \( s \geq 140 \). This means the train's speed must be at least 140 miles per hour to meet the cruising standard. For the runner qualifying for the championship, the inequality can be expressed as \( t \leq 55 \). This indicates that to qualify, the runner's completion time must be 55 minutes or less, ensuring they meet the championship criteria.
