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:

30+15

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
