Hello!
We know that Isaac played 20 games and won about 70% of them. Now, we must find what 70% of 20 is, so that we know how many games Isaac won. 
First, convert the percentage to a decimal by dividing it by 100. 
70% ÷ 100 = 0.70 
Next, multiply the total amount of games Isaac played (20) by about how many he won (0.70): 
20 × 0.70 = 14
ANSWER: 
Isaac won about 14 games.

The answer is <span>9.55 minutes
</span>
1. Turn 15 km into miles:
    1 km = 0.621 mile
    15 km = 15 * 0.621 mile = 9.315 miles
So, she ran 9.315 miles for 89 minutes
2. Calculate <span>how many minutes it took Jimena to run 1 mile during the race:
    S</span>he ran 9.315 miles for 89 minutes.
    She ran 1 mile for x minutes.
    9.315 mi : 89 min = 1 mi : x
    x = 89 min * 1 mi / 9.315 mi
    x = 9.55 min
