Answer:
17.5 miles per hour
Step-by-step explanation:
A boat travels upstream on a Mississippi river for 3.5 hours
The return trip takes 2.5 hours
The boat travels 2 miles per hour faster downstream
Let y represent the speed that was travelled upsteam
3.5y = 2.5(y + 2)
3.5y = 2.5y + 5
3.5y - 2.5y = 5
y = 5
Therefore the distance travelled by the boat upstream can be calculated as follows
= 3.5 × 5
= 17.5 miles per hour

Answer:
<h2>8 units.</h2>
Step-by-step explanation:
The complete question is
<em>A scale factor of 1/3 is used to make a reduction, as shown in table below.</em>
<em>What is the base of the reduced triangle?</em>
- <em>4</em>
- <em>8</em>
- <em>9</em>
- <em>21</em>
According to the given table, the original base is 24. If the given scale factor is applied, the reduced base would be

Remember that a scale factor is a number that multiples the figure, a scale factor can reduced or amplify a figure.
Therefore, the reduced base is 8 units.
