Christy's family took a trip to Georgia this summer. The distance from Christy's town to Georgia was 432 miles. Christy's dad wanted to drive the trip without stopping and make it to Georgia in 12 hours. What average speed would Christy's dad have to maintain in order for the trip to take exactly 12 hours?

36 Miles

Step-by-step explanation:

432/12 = 36

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
