Answer:

5 MB.

Explanation:

1 foot = 12 inches

2400/9=266.66 feet per track

1 track excluding, remaining 8 track =2400 - 266.66 = 2133.33 feet

so, space available to store data = 2133.33 feet

now, 2133.33 feet = 25600 inches

total data that can be stored = 25600 * 1600 = 40960000 bits

= 46080000/8 = 5120000 Bytes

= 5120000/1000000 = 5.12 MB = 5 MB (approx.)
