Answer 1

Complete Question:

Haruka hiked several kilometers in the morning. She hiked only 6 kilometers in the afternoon, which was 25% than she had hiked in the morning.

How many kilometers did Haruka hike in all?

Answer:

10.5 km

Step-by-step explanation:

Given

Represent Morning with M and Afternoon with A

$A = 6km$

From the second sentence in the question, we have that:

$M = A - 25\% * A$

Required

Determine the total kilometers

First, we need to determine the kilometers moved by substituting 6 for A in the second equation

$M = A - 25\% * A$

$M = 6 - 25\% * 6$

$M = 6 - 1.5$

$M = 4.5$

Next, is to determine the total using:

$Total = A + M$

$Total = 6 + 4.5$

$Total = 10.5\ km$
