Question

The distance driven in miles is proportional to the time driven in hours. Ebony drives at a constant rate and plots her progress on a coordinate plane. The point (3, 180) is plotted. At what rate is Ebony driving in miles per hour?
A)40 mph
B)50 mph
C)60 mph
D)70 mph

Answer 1

Okai so Rate= distance divided by time

Answer 2

Here the independent variable is time and the dependent variable is the distance

Answer 3

?

Answer 4

X is the independent variable therefore X is time
Y is the dependent variable therefore Y is distance.

Usually when you write a point of a graph the first is X and then Y
(X,Y)
Therefore here X= 3
Y= 180
I said earlier that X= time
Y= distance
Therefore Distance = 180 miles
Time = 3 hours.
So now find the rate.

Answer 5

Rate= distance/ time = 180/3 = 60mph
