The answer is <span>2.5 × 10⁻⁹ × 1.5 × 10³ = 3.75 × 10⁻⁶ </span>
There is a formula for that;
Total time = (Worker 1 * Worker 2) / (Worker 1 + Worker 2)
Total time = (80 * 120) / (80 + 120)
Total time = 9,600 / 200
Total time = 48 minutes
|-5| - |7 - 4|
First, simplify |-5| to 5. / Your problem should look like: 5 - |7 - 4|
Second, simplify 7 - 4 to 3. / Your problem should look like: 5 - |3|
Third, simplify. / Your problem should look like: 2
Answer: 2
