Answer:
4 miles per hour
Step-by-step explanation:
To get 1 hour from 1/6 an hour you need to multiply it by 6. You also multiply
the miles walked in 1/6 and hour which is 2/3. When you multiply both you will get 4 miles per hour.

The quantity of each concentrations of 3% and 9% needed to get the desired concentration is 54 milliliters and 27 milliliters respectively
<h3>Simultaneous equation</h3>
Let
- Quantity of 3% needed = x
- Quantity of 9% needed = y
x + y = 81
0.03x + 0.09y = 81 × 5%
0.03x + 0.09y = 4.05
x + y = 81
0.03x + 0.09y = 4.05
From (1)
x = 81 - y
0.03x + 0.09y = 4.05
0.03(81 - y) + 0.09y = 4.05
2.43 - 0.03y + 0.09y = 4.05
- 0.03y + 0.09y = 4.05 - 2.43
0.06y = 1.62
y = 1.62/0.06
y = 27
x = 81 - y
x = 81 - 27
x = 54
