Answer: The actual height of train = 4.896 meters.
Step-by-step explanation:
Since we have given that
Lina has a scale model of a modern train
Model is created at a scale is given by
1:48
Height of the model train = 102 millimeters
We need to find the actual height of the train.
Since there is direct variation between model and actual height of the train.
According to question,

Hence, the actual height of train = 4.896 meters.
-8
f(-1/2)=10(-1/2)-3
f(-1/2)=(-5)-3
f(-1/2)=-8
WEW can use a simple equation to solve this
Let x be the number of kilometers she hiked in the morning . Then
x - 0.25x = 6 (Note 0.25 = 25 %)
0.75x = 6
x = 6 / 0.75 = 8 kilometers answer
