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.

Sanjay has 3 2/3 yards of yellow ribbon and 5 2/3 yards of blue ribbon. How many yards of ribbon does Sanjay have altogether? A.

Klio2033 [76]

This is exactly like the last question you posted. First you have to change the 3 and 2/3 mixed fraction into a pure fraction. 3 and 2/3 = 9/3 and 2/3 = 11/3 "eleven thirds." You now just need to divide (11 / 3) by (2/3.) (11 / 3) / (2 / 3) = (11 / 3) * (3 / 2) = 11 / 2 = 5 and 1/2 pieces. So if Mae cuts the ribbon into pieces that are 2/3 yard long, Mae will end up with 5 and 1/2 pieces. Checking our work, 5 pieces would be 5 * (2/3) = 10 / 3 = 3 and 1/3 yard long, leaving us with an extra 1/3 yard of ribbon, which is the "half piece" we got. Depending on the phrasing of the question, the answer could be "Mae makes 5 and a half pieces." or "Mae can make 5 pieces, and will have 1/3 yard of ribbon left over."
the answer is C. 9 1/3
Hope this helps!
