Eliza is driving from Cleveland the graph representing her distance d from cleveand in miles and the number of hours she drives has a slope 50 and h intercept 800 a what is eliza's average speed?
Her average speed is 50 mph.
If the graph represents her distance (how many miles driven) as
well as the number of hours driven, then the slope, which is rise
divided by run, then the y axis, which in this case refers to the
distance driven (y is the vertical axis, and the h [height]
intercept is 800 which must refer to the distance) divided by the x
axis (number of hours traveled) gives the average speed (miles per
hour, miles divided by hour).
The average speed is therefore 50 mph. The distance traveled is
800 miles, and the time traveled is 16 hours.
