Julia rides her horse 18 km with a constant speed of 6km/hr and another 24 km with a constant speed of 12 km/hr. What is her ave

nlexa [21]

Answer:

8.4 km/hr.

Step-by-step explanation:

We have been given that Julia rides her horse 18 km with a constant speed of 6 km/hr.

Let us find the time taken by Julia to cover a distance of 18 km.

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

$\text{Time taken to cover 18 km}=\frac{18\text{ km}}{\frac{6\text{km}}{\text{hour}}}$

$\text{Time taken to cover 18 km}=\frac{18\text{ km}}{6}\times\frac{\text{hour}}{\text{km}}$

$\text{Time taken to cover 18 km}=\frac{18}{6}\times\text{hour}$

$\text{Time taken to cover 18 km}=3\text{ hour}$

We are also told that she rides another 24 km with a constant speed of 12 km/hr.

Let us find the time taken by Julia to cover a distance of 24 km.

$\text{Time taken to cover 24 km}=\frac{24\text{ km}}{\frac{12\text{km}}{\text{hour}}}$

$\text{Time taken to cover 24 km}=\frac{24\text{ km}}{12}\times\frac{\text{hour}}{\text{km}}$

$\text{Time taken to cover 24 km}=\frac{24}{12}\times\text{hour}$

$\text{Time taken to cover 24 km}=2\text{ hour}$

Since we know that $\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}$ .

Upon substituting our values in above formula we will get,

$\text{Julia's average speed}=\frac{18\text{ km}+24\text{ km}+}{3\text{ hour}+2\text{ hour}}$

$\text{Julia's average speed}=\frac{42\text{ km}}{5\text{ hour}}$

$\text{Julia's average speed}=\frac{8.4\text{ km}}{\text{ hour}}$

Therefore, Julia's average speed is 8.4 km per hour.

9(m - 3) + 3m = 7m + 43

frozen [14]

$\begin{gathered} 9(m-3)+3m=7m+43 \\ \text{Multiply the parenthesis by 9 and you have} \\ \\ (9\times m-9\times\lbrack-3\rbrack)+3m=7m+43 \\ \text{Next you have} \\ 9m-27+3m=7m+43 \\ \text{Note that the 9 multiplies the m to get 9m,} \\ \text{and the 9 also multiplies the negative 3 to arrive at negative 27.} \\ \text{After applying 9 to open the parenthesis, you now have } \\ 9m-27+3m=7m+43 \\ \text{You collect like terms. In this case all expressions that have m are like terms} \\ \text{The ones that does not have m are also like terms but, separate} \\ \text{Collect like terms with m on to the left hand side} \\ 9m+3m-7m=43+27 \\ \text{Note that whenever a positive number moves over across the sign of equality,} \\ it\text{ becomes a negative number and vice versa.} \\ \text{Hence 7m has moved and now becomes -7m} \\ \text{Also -27 has moved and now becomes +27} \\ 9m+3m-7m=43+27 \\ 5m=70 \\ \text{Divide both sides by 5 to eliminate it from the left side} \\ \text{and hence m would now stand alone} \\ \frac{5m}{5}=\frac{70}{5} \\ m=14 \end{gathered}$
