Answer:
54mph
Step-by-step explanation:
To find the speed in "miles per hour" or miles/hour, divide the number of miles by number of hours.
1080 miles/20 hours
= 54miles/hour
His speed is 54 miles per hour.

There is no solution. 2(x-1)^2 = 3-5 (x-1)^2 = -1 you will get an imaginary solution
Answer:
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is: 
Step-by-step explanation:
Given points are:
(-5,3) and (3,7)
The perpendicular bisector of line segment formed by given points will pass through the mid-point of the line segment.
First of all we have to find the slope and mid-point of given line
Here
(x1,y1) = (-5,3)
(x2,y2) = (3,7)
The slope will be:

The mid-point will be:

Let m1 be the slope of the perpendicular bisector
Then using, "Product of slopes of perpendicular lines is -1"

We have to find the equation of a line with slope -2 and passing through (-1,5)
The slope-intercept form is given by:

Putting the point (-1,5) in the equation

The final equation is:

Hence,
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is:
