If a person walks 2.4 miles in1.5 hours, how far can he walk in 3 hours

The person can walk 4.8 miles in 3 hours.

Step-by-step explanation:Given :

A  person walks 2.4 miles in 1.5 hours.

Then, the ratio of distance to time =  (1)

Let x be the distance he waked in 3 hours.

Then, the ratio of distance to time = (2)

We assume that he moves at constant rate, then from (1) and (2) , we have

Multiply 3 on both sides , we get

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

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
