if a person walked 3/4 mile in 12 minutes . how long would it take to walk three miles at this pace

3/4/(12) = 3/4*1/12 = 3/48 = 1/16 mi/min.

3/(1/6) = 3 * 6/1 = 18 min.

x/3 = 12/(3/4) = 12 * 4/3 = 48 min

To determine how long it would take to walk three miles at the same pace, we can use the concept of proportion.

Let's calculate the time it takes to walk 1 mile at this pace first:

1 mile = 3/4 mile * (12 minutes)
1 mile = 9 minutes

Now that we know it takes 9 minutes to walk 1 mile, we can find the time it takes to walk three miles:

3 miles = 3 * (9 minutes)
3 miles = 27 minutes

Therefore, it would take 27 minutes to walk three miles at this pace.

To determine how long it would take to walk three miles at the same pace, you can use a proportion to solve the problem.

The ratio between distance and time is constant for a given pace. In this case, the ratio is 3/4 mile per 12 minutes.

Let's set up the proportion:

(3 miles) / (x minutes) = (3/4 mile) / (12 minutes)

To solve this proportion, you can cross multiply:

3 * 12 = (3/4) * x

36 = (3/4) * x

To isolate x, divide both sides of the equation by 3/4:

x = 36 / (3/4)

To divide by a fraction, you can multiply by its reciprocal (the flipped version of the fraction):

x = 36 * (4/3)

Simplifying the expression:

x = 48

Therefore, it would take 48 minutes to walk three miles at the same pace as walking 3/4 mile in 12 minutes.
