Answer:

154 km

Step-by-step explanation:

Haruka hiked several kilometers in the morning. She hiked only 66 kilometers in the afternoon, which was 25% less than she had hiked in the morning.  How many kilometers did Haruka hike in all?

Let x = no. of km that Haruka hiked in the morning

      y = no. of km that Haruka hiked in the afternoon = 66 km

Required: Total no. of km that Haruka hiked

Solution:

66 = x - (0.25)(x)

66 = 0.75x

x = 88 km

total km hiked = 66 + 88 = 154 km
