Answer 1

IT c I took the test

Answer 2

C. 125

Explanation:

The ratio for one time is 3:6. It is 3:6 because there are 3 numbers less than 4 on a number cube. You can now compare the two ratios.

3:6 = x/250.

This is a ratio, so both numbers would have to be multiplied by the same number. 6 * 41 = 250.

3 * 41 = 123.

(41 was rounded from 41.6666667. This is why it comes out to 123.)
