If joseph runs 1/5 mile in 1/30 of an hour, what is his speed in miles per hour?

6 miles per hour

Step-by-step explanation:

1/30 of an hour is 2 minutes

he ran 1/5 of a mile in 2 minutes so

5/5 of a mile = 1 mile  

5 x 2 min = 10 minutes

Take 6 x 10 minutes to = 1 hour

So 6 x 1 hour is 6 miles and hour.

a is the right answer

Step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
