If a person walks 2.4 miles in 1.5, how far can he walk in 3 hours

1.5 hours?

2.4 * 2 = ?

Since 3 hours is twice 1.5 hours, I just doubled 2.4 hours.

You could also use a proportion. Cross multiply and solve for x.

2.4/1.5 = x/3

1.5x = 7.2

x = 4.8

The answer is 4.8!

To calculate how far a person can walk in 3 hours, we need to determine their average walking speed.

First, we need to find the average speed of the person's walk. We can do this by dividing the distance they walked by the time taken:

Average Speed = Distance / Time

In this case, the person walked 2.4 miles in 1.5 hours:

Average Speed = 2.4 miles / 1.5 hours

Calculating the average speed, we get:

Average Speed = 1.6 miles per hour

Now that we have the average speed, we can calculate how far the person can walk in 3 hours. To do this, we multiply the average speed by the time:

Distance = Average Speed * Time

Substituting the values, we get:

Distance = 1.6 miles per hour * 3 hours

Calculating the distance, we find:

Distance = 4.8 miles

Therefore, the person can walk 4.8 miles in 3 hours.
