Step by Step Solution:
Answer:
110 students walk or bike to school.
Step-by-step explanation:
48% of the 208 students walk, whereas 5% bike. Combining 48% and 5%, we get 53%.
53% of the total number, n, comes to 208 students.
This number is 0.53(208 students), or 110 students.
110 students walk or bike to school.
100*2.2=220
80*2=176
220+176=396
So the two trains will take 2.2 hours so that they are 396 miles apart.
