Isla runs 800m in 10 minutes

800/10 = 80

Isla runs 80m in 1 minute

80 x 50 = 4000

Isla runs 4000m in 50 minutes

4000m = 4km

To find out how many kilometers Isla can run in 50 minutes, we can use a proportion based on her running rate.

We know that Isla can run 800 meters in 10 minutes. Let's set up a proportion to find the distance she can run in 50 minutes:

Distance in meters / Time in minutes = Distance in meters / Time in minutes

800 meters / 10 minutes = x kilometers / 50 minutes

To solve for x, we cross-multiply and then divide:

(800 meters) * (50 minutes) = (10 minutes) * x kilometers

40,000 meters = 10x kilometers

Dividing both sides by 10:

40,000 meters / 10 = x kilometers

4,000 meters = x kilometers

Therefore, Isla can run 4,000 meters (or 4 kilometers) in 50 minutes.

I hope this helps! :)
