Answer:
0.25 miles
Step-by-step explanation:
The total distance off from her school is obtained by subtracting the distance traveled in a bus plus the distance walked from the total distance.
Given that she walks for half a mile and travels 2 miles in the bus:
[tex]d_r=d_t-(d_w+d_b)\\\\=2\frac{3}{4}-(0.5+2.0)\\\\=0.25\ miles[/tex]
Hence, the bus drop her 0.25 miles off from school.
