Biking at 8 mph, it takes kristen 1/4 hour to reach the train station to go to work. kristen then takes the train to work, and it takes another 1/4 hour for her to get to work when the train travels 24 mph. how far does kristen travel to work?

8 miles.

Step-by-step explanation:

Biking at 8 miles per hour for 1/4 an hour is equal to biking 2 miles.

Riding the train at 24 miles per hour for 1/4 an hour is equal to riding 6 miles.

2 miles + 6 miles = 8 miles.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
