You would divide 30 meters by 20 seconds. If you want to know how many meters he can run per second, you divide the amount ran (30 meters) by the amount of seconds (20 seconds). This would tell you the amount per second.

The answer would be 1.5 meters/second.

- - He runs 1.5 meters each second.

- Solve:
Divide 30/20
=1.5
To answer this we will divide the amount of meters by the amount of seconds. Then your answer will be the amount of meters Earl runs per second. Then we will check our work. Lets do it:-

30 ÷ 20 = 1.5
1.5 meter per second.

CHECK OUR WOK:-

1.5 × 20 = 30
We were RIGHT!!

So, 1.5 meters per sec.

Which statement can be used to prove that a given parallelogram is a rectangle?

RSB [31]

The correct answer is:

The diagonals of the parallelogram are congruent.

Explanation:

In every parallelogram, opposite angles are congruent. This would not mean it is a rectangle.

Consecutive sides of a parallelogram are only congruent if the parallelogram is a rhombus or a square; this would not be a rectangle.

The diagonals of every parallelogram bisect each other. This would not mean it is a rectangle.

The diagonals of a rectangle bisect each other. If we know this is true about our parallelogram, this means our parallelogram is a rectangle.
