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

Answer:

C.

Step-by-step explanation:

The first thing is to go to the information given by the statement of the question.

We have mentioned two crucial things:

The first that time and distance are proportional.

The second is the coordinates, (3,180). Assuming 3 is hours and 180 miles:

Since they are proportional to do the calculations, both points must be divided by the same number.

First, if we divide by 1, we would be equal, 1 and 180.

Second, if we divide by 2, we have 1.5 (3/2) and 90 (180/2) left, and these values are not in the answer options.

Third, if we divide by 3, we have 1 (3/3) and 60 (180/3) left, we have to be a speed of 60 miles in one hour. Being the answer C.

Answer 2

Answer:

C) 60 mph.

Step-by-step explanation:

If Ebony covers 180 miles in 3 hours as seen in the point (3, 180)

Distance=180 miles; Time = 3 Hours

Driving Rate=Distance/Time = 180/3 = 60mph
