Answer:10

Step-by-step explanation:Set up the following proportion.

2 questions /15 minutes = x questions / 75 minutes.

Notice that both ratios are set up the same way — questions / time. All proportions are set up the same way.

Mulltiply both sides by 75

2 * 75 / 15 = x

2 * 5 = x

x = 10

She would be able to solve 10 problems in 75 minutes.

10.

Because the ratio is how many problems:How much time so it is 2:15

Multiply each side by 5 10:75

So that means 10 problems in 75 minuets.

HOPE THIS HELPED!!!
