If I drive 42 miles per hour how far do I drive in 3 hours

Work Shown:

1 hour = 42 miles

3 hours = 126 miles (multiply both sides by 3)

or you can do it this way

distance = rate*time

d = r*t

d = 42*3

d = 126

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
