Atrain goes at a constant speed. if it covers 150 miles in 2 1/2 hours what distance would it cover in 3 hours?

It would cover 180 miles in 3 hours

Step-by-step explanation:

Distance traveled =150 miles

Time taken to travel 150 miles =

                                                   =

So, Speed of train = 60 miles per hour

Now we are supposed to find distance covered in 3 hours

Time = 3 hours

Speed of train = 60 miles per hour

Hence it would cover 180 miles in 3 hours

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
