Where Math Gets Real
1A. RTS Lab in Iran uses drones to deliver life preservers to drowning swimmers near shore or in open seas. Depending on how far out a swimmer is, it takes the drone at least 5 seconds and no more than 70 seconds to deliver a life preserver. Express this range as an inequality using the variable p .
1B. Graph the inequality on the number line below.

Where Math Gets Real
Defibrillators are devices that deliver a dose of electric current to the heart when it’s not beating properly. A German company developed a drone to deliver defibrillators to emergency responders using a smartphone app.
1A. The drone can travel no more than a distance of 6 miles from the operator. Express the range as an inequality using the variable m .
1C. If the drone travels at a speed of at least 23 miles per hour and at most 43 miles per hour, what is the range of time it will take the drone to deliver a defibrillator to a person who is 4 miles away?
Express the range as an inequality where t represents the drone’s delivery times.
1B. Graph the inequality on the number line below.
1D. Graph the inequality on the number line below.
