Art [367]

Answer:

43.5625 kilometers

Step-by-step explanation:

hi!

To solve this problem, you have to take note of the important information which is:

- 10.25 km/hour

- 4.25 hours

- how far did she travel?

To answer the question, you need to take Mia's hourly rate (10.25 km PER hour) and multiply that by how many hours she rode her bike for (4.25) which equals 43.5625 kilometers

10.25*4.25 = 43.5625 kilometers

I hope this helped :)

zmey [24]

Answer:

Harukah hiked for 14 km in all.    

Step-by-step explanation:

We are given the following in the question:

Hike in afternoon = 6 km

Let Haruka hike x km in the morning.

We are given the relation:

6 = x - 25\%(x) \\\\6 = x - \dfrac{25}{100}\times x\\\\6 = 0.75x\\\\x = \dfrac{6}{0.75}\\\\x = 8

Thus, Haruka hiked for 8 km in the morning.

Total hike length of Harukah =

=6 + 8\\=14\text{ km}

Thus, Harukah hiked for 14 km in all.
