Christy drove 300 miles on her vacation. She drove 1.25 time faster on the second 150 miles of her trip than on the first. Which expression represents the time she spent driving? Let x be her speed for the fist half.

a. 375/x
b. 33.5/x
c. 270x
d. 270/x

1st half speed --- x

2nd half speed -- 1.25x

Since time = distance/rate

time for 1st part = 150/x
time for 2nd part = 150/1.25x

total time = 150/x + 150/1.25x
LCD = 1.25x
total time = (150(1.25) + 150)/1.25x
= 337.5/1.25x
= 270/x

Y’all, don’t listen to the test answers. For math, all of the tests are different per student. I know this cause me and my sister are in the same class and have different problems. That’s why y’all keep saying each other are wrong

This could be avoided if people just typed the first 3 words of a question and then put the answer after

guys the answers change btw! try to look for people who actually give the answers instead of the letter, or just look on brainly instead :) hope everyone is doing well

Are any of you people in connections academy

idk what yall are doing by putting your test answers on here. it wont help others since every test is different. sure they may have the same questions but the tests shift the questions around so that no ones test is the exact same. hence the reason that everyone that used the test answers got a failing grade on their test. They are NOT THE SAME!! my advice is to just try your best, you'll get a better score that way.

b is actually 337.5/x.

uh no

Most of the answers for everyone will be incorrect for others. If you want to, i highly, HIGHLY recommend getting an app called mathway. Its been extremely helpful throughout the whole year for me. And if you cant get an answer from it, you can google. (Thats what i do with word problems) and for those you can almost alwase count on brainly. Jiskha is still my go to for quizzes and such though.

Ms.Smart IS NOT CORRECT!!!!!! DO NOT USE HER ANSWERS!!!!!!!!! I JUST TOOK THE TEST AND GOT A ZERO!!!!!! I ONLY GOT 2 CORRECT!!! LIAR!!!! YOU'RE BETTER OFF DOING IT YOURSELF!!!!!
