No, 11/5 simplified is 2 1/5 so it is in between 2 and 3
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
Answer:
x = 13 1/2 or 13.5
Step-by-step explanation:
Flip Equation
-38 - 12x = -200
-12x -38 = -200
Add 38 to both sides
-12x -38 + 38 = -200 + 38
-12x = -162
Divide
-12x/-12 = -162/-12
x = 27/2
Simplify
27/2 = 13 1/2
x = 13 1/2
