Final answer:
Mary can run approximately 3.33 km in 25 minutes at the same pace she ran 2 km in 15 minutes, calculated by determining her speed and applying it to the extended time.
Step-by-step explanation:
If Mary ran 2km in 15 minutes, to find out how far she can run in 25 minutes, we can use the concept of ratios to solve this problem. We'll first calculate her speed per minute and then use that to find out the distance she can cover in 25 minutes.
Step-by-step calculation:
- Find the speed: Speed = Distance / Time = 2km / 15min = 0.1333... km/min.
- Calculate the distance for 25 minutes: Distance = Speed * Time = 0.1333... km/min * 25 min = 3.333... km, which we can round to 3.33 km (or 3333 meters).
Therefore, at the same rate, Mary can run approximately 3.33 km in 25 minutes.
To determine Mary's potential distance in 25 minutes, we employ the ratio of her known speed. Initially running 2 km in 15 minutes implies a speed of 0.1333 km/min. Applying this speed to 25 minutes yields an approximate distance of 3.33 km.
