A rounded number for the speed of an insect Is 5.67 meters per second. What are the fastest and slowest speeds to the thousandths that could round to 5.67? Explain.

We can round numbers in two ways: rounding up or rounding down.

Number 5 is in the middle and it goes up:

For example: 5.665 ≈ 5.67, but 5.664 ≈ 5.66

Also: 5.675 ≈ 5.68 and 5.674 ≈ 5.67

Answer:

The fastest speed to the thousandths: 5.674 m/s

The slowest speed to the thousandths: 5.665 m/s
