Question

If a person walks 1/2 mile in 1/4 hour, how far does that person walk in 1 3/4 hours at that rate?​

Answer 1

3 1/2 miles

Explanation:

We can use a ratio to solve

1/2 mile x miles

----------------= ---------------

1/4 hour 1 3/4 hours

Changing to improper fractions

1/2 mile x miles

----------------= ---------------

1/4 hour 7/4 hours

Using cross products

1/2 * 7/4 = 1/4x

7/8 = 1/4x

Multiply each side by 4

7/2 = x

Changing back to a mixed number

3 1/2 =x
