Final answer:
Erin's speed is 0.2 kilometers per minute. Mustafa runs 0.575 kilometers by converting 575 meters to kilometers.
Step-by-step explanation:
The question asks for Erin's speed in kilometers per minute based on her running 5 km in 25 minutes. To find the speed, we divide the distance traveled by the time taken to travel that distance.
Erin's speed (in km/min) = Distance (in km) ÷ Time (in minutes)
Erin's speed = 5 km ÷ 25 min = 0.2 km/min
Thus, Erin's speed is 0.2 kilometers per minute.
In the concept example, Mustafa runs 575 meters, which he converts to kilometers. As there are 1,000 meters in a kilometer, he divides by 1,000.
Mustafa's distance in km = 575 m ÷ 1,000 = 0.575 km.
