Question

Question 2There are 12 inches in 1 foot and 5,200 feet in 1 mil. Elenaran 2 1/2 miles1. How many feet is that?2. How many inches is that?

Answer 1

We are given that Elena ran 2 1/2 miles.

First, convert the mixed fraction to proper fraction.

$2\frac{1}{2}miles=\frac{2\cdot2+1}{2}=\frac{4+1}{2}=\frac{5}{2}miles$

Now we are also given that there are 5,200 feet in 1 mile.

So we can convert the miles into feet as,

$\frac{5}{2}\cdot(5,200)=13,000$

Therefore, Elena ran 13,000 feet.

Similarly,

We are also given that there are 12 inches in 1 foot.

So we can convert the feet into inches as,

$13,000\cdot(12)=156,000$

Therefore, Elana ran 156,000 inches.
