Math ? easy but i can't get it! : (
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
eliminate
c)
60 mph
d)
70 mph

Ok, so, the question states that the distance driven is proportional to the time driven in hours. So, the x value would be hours driven, while the y-value would be the number of miles driven. So, in order to find the speed at which she is driving, you will want to divide the number of miles by the number of hours driving, or 180/3, You answer should be 60, or 60 mph is her speed.
