If a person runs 10 kilometers in 0.4 hours, at what speed are they running per hour? I Need a explanation

62.5 i think use a calculater i...

divided 25 by 0.4 got 6.25

6.25 times 10 got 62.5

Step-by-step explanation:

done i hope its right sorry if its not

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

step-by-step explanation:

ask goog great chance of finding the solution there
