How many inches are there in 2.5 miles? There are 5,280 feet in one mile and there are 12 inches in one foot.

A 13,200 inches
B 158,400 inches
C 30 inches
D 1,100 inches

To find the number of inches in 2.5 miles, we will first convert miles to feet and then feet to inches.

1 mile = 5,280 feet

So, 2.5 miles = 2.5 * 5,280 feet = 13,200 feet

Since there are 12 inches in one foot, we can multiply the number of feet by 12 to get the number of inches.

13,200 feet = 13,200 * 12 inches = 158,400 inches

Therefore, the answer is option B) 158,400 inches.
