A train left a station at 8:13 a. m. arriving at its destination at 4:52 p. m. If the stations are 709.3 miles apart, calculate the average speed at which the train
traveled.
OA. 82 miles/hour
OB
93 miles/hour
OC. 72 miles/hour
OD. 92 miles/hour

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
