1.) Amy travels 27.5 miles to get to work by car. The first part of her trip is along a country road on which she averages 35 miles per hour, and the second part is on a highway where she averages 48 miles per hour. If the time she travels on the highway is 5 times the amount of time she travels on the country road, what is the total time for the trip?
2.) A taxi charges 80 cents for the first 1/6 mile and 20 cents for each additional 1/6 mile. if a passenger paid , how far did the taxi travel?
3.) A financial advisor invested an amount of money at an annual rate of interest of 9%. She invested 00 more than this amount at 12% annually. The total yearly income from these investments was 94. How much did she invest at each rate? T=1

What do you think? Answer below!
i have no clue….. its satreday:P
No way. Do your own homework.
“Please show me the work”?!?!?
Are you kidding?
Do it yourself.
1) basically she travels 1/5 * 27.5 miles on the country roads, and 4/5 * 27.5 on the highway, so 5.5 miles on the country and 22 miles on the highway. since she travels 35 mph on the country road, you do 35/60 = .58333, so basically .5833 miles a minute. divide 5.5 by .5833 and get about 9.43 minutes total on the country road. Now do the same thing for the highway and get about 27.5 minutes on the highway. Add those for a total of about 36.93 minutes
2) Easy, 5.2/.2 = 26 which is the number in sixths the taxi has traveled after the initial 1/6 mile. Then multiply 26 *1/6 which is 4 and 1/3, make sure you add the initial 1/6 mile which = a total of 4.5 miles
Haha I really dont have the time to answer any more maybe somebody else can
Come on! These are simple questions, the kind you would do in primary school! Well at least i did, I don’t know about you! You don’t need to get someone else to do your homework for you! You are better than this!
Geez, when I was given these kind of questions for homework I didn’t have the luxury of going on the internet and getting the answers, even if I did I wouldn’t have because in the long run who are you fooling? not you teacher, just yourself!
at least attempt to do your questions and if you cannot do one or two of them talk to you teacher and he/she should bring you up to speed.
