a train traveled 90 miles in 1 1/2 hours. How many miles will it travel in 6 hours going at the same rate.

360 miles

Step-by-step explanation:

if 90 miles per hour and a half then

1 1/5 x 4= 6

90 x 4 = 360

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.
