Question

Ja’Nay ran 3/4 of a mile in 1/8 of an hour. At this rate, how far can she run in 1 hour

Answer 1

6 miles per hour

Explanation:

we'll set up the problem like this:

3/4 mi = 1/8 hr

now multiply each side by 8:

24/4 mi = 1 hr

simplify:

6 mi = 1 hr

Answer 2

Explanation:

If it takes her 1/6 per hour to run half a mile. Let's see how long she can run in one hour.

To get from 1/6 hour to 1 hour .. we need to multiply by 6.

6 * 1/6 = 1

We will now also need to multiply her distance by 6

1/2 * 6 = 6/2 = 3

Now we know she runs 3 miles in one hour. Which is also her speed. 3mph
