Ivanna runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?

Step-by-step explanation:

Mia 's running rate = 6 miles/ 50 minutes = 3/25 mi per minute

Rate = distance/ time

3/25 = distance / 35

3/25 * 35 = distance

4.2 = distance

so she can run 4.2 miles

Try this option:
1. according to the condition Kris scored '2x' points, Julio did 'x' points (Kris scored 2 times as many points as Julio).
2. according to the condition Kris'_points+Julio's_points=36_points. It means, that x+2x=36.
3. If to solve this equation (2x+x=36), then Julio scored x=12 points, Kris scored 2x=12*2=24 points.

12 (Julio); 24 (Kris).
