Answer:
the bus drop him off 0.5 miles from the school
Step-by-step explanation:
Total miles = 3.5 miles (3 1/2 miles)
bus stop distance = 0.25 miles
city bus = 2.75 miles (2 3/4 miles)
Before Nigel gets to school de distance is 3 miles. Then, reading the text, the bus drop him off 0.5 miles from the school. In other way
3 + X = 3.5 → X= 3.5-3 = 0.5 miles
