The horse racing record for a 1.50 mi track is shared by two horses. fiddle isle, who ran the race in 143 s on march 21, 1970, and john henry, who ran the same distance in an equal time on march 16, 1980. what were the horses' average speeds in: a. mi/s

we know that

the average speed is equal to

in this problem we have

substitute the values in the formula

i think the correct option is the second option.

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.
