The formula f = 5280m can be used to convert a measurement of f feet to an equivalent measurement of m miles. if an airplane flies at 35,300 miles above the ground, how much is that in feet?

a 186,384,000 feet

b 6.7 feet

c 194,234,000 feet

d 7.2 feet

Option A

If an airplane flies at 35,300 miles above the ground, then it is 186384000 in feet

Solution:

Given that  

Formula f = 5280m can be used for measurement of f feet to an equivalent measurement of m miles.

Given that airplane flies at 35,300 miles above the ground . need to calculate how much feet is airplane above the ground.

Means need to calculate f when m = 35300 miles  

On substituting m = 35300 in given formula , we get

Thus Option A is correct.

x/3-10=8

x/3=18

x=48
