Sal is participating in a charity walk. the distance sal walks, in kilometers, is proportional to the number of hours he spends walking.
which statements are true about the distance sal walks?
select each correct answer.

a. sal walks 1 km in 3.5 h.

b. sal walks 14 km in 4 h.

c. sal walks 4 km in 14 h.

d. sal walks 3.5 km in 1 h.

B.Sal walks 14 km in 4 h.

D.Sal walks 3.5 km in 1 h.

Step-by-step explanation:

Given : The distance Sal walks, in kilometers, is proportional to the number of hours he spends walking.

From the given  graph , it can be seen that the x-axis is representing Time ( in hours) and the y-axis is representing Distance ( in km).

Since the relationship between distance( in km) and time is time ( in hours) is given to be proportional , therefore there is a straight line in which each point is describing time taken by Sal to cover a particular distance.

i.e. x-coordinate = Time taken by her.   ( independent variable)

y-coordinate = Distance covered by her at that time. ( dependent variable)

⇒Point (1,3.5) tells that Sal walks 3.5 km in 1 h.

[∵ x-coordinate=1 , y-coordinate=3.5]

and Point  (4, 14)  tells that Sal walks 14 km in 4 h.

[∵ x-coordinate=4 , y-coordinate=14

Hence, the correct options are :

B.Sal walks 14 km in 4 h.

D.Sal walks 3.5 km in 1 h.
