Question 113764This question is from textbook Algebra Structure and method
: At 8:00 a.m the Smith's left a campground,driving at 48mi/h. At 8:20 a.m the Garcia's left the same campground and followed the same route, driving at 60 mi/h. At what time did they overtake the Smith's?
Here is what I have but I don't know if it is right
60t=48(t+1/3)
60t=48t+16
60t-48t=48t-48t+16
12t=16
12t/12=16/12
t=14/12or 11/3
They overtook the Smiths at 1:20

Question 114892: Hisako ran a cross-country race in which the course was divided into 3 equal legs. Hisako ran the first leg at 12 km/h and the last two legs at 16 km/h. The whole race took her 50 min. How long was each leg? How long was the entire course?
I know the solution is something like this:
12t + 16t + 16t = d
And I believe 50 minutes needs to be converted to hours, so 5/6 of an hour...but I'm not sure how to set up the equation so it's solvable. Please help.

Question 114934: Alexandra lives 33 miles from work. During the summer she rides her bike at 7mph to the metro station. She then takes the metro to work which travels at 39mph.
If she spends 21 min more on the bike than on the metro,what is the distance from her house to the metro?(work with time in hours and round your answer to a whole number.
Here is what I have tried: the total distance is 33 miles from home to work. The distance from home to the metro is 33-x. THe time x +.35 hr.= TIME ON THE METRO, I think. I tried 7(x)+39(x+.35
7x¨plus 39x plus 13.65equals33 x equals .42 hr that is the time biking 7x.42equals 2.94 miles. round to 3 miles.Is this right

Question 115995This question is from textbook
: I've been working on this one for two days. Any help is appreciated.
Girl is hiking and standing on the middle of a train bridge over a river. She is 300 ft from point P which is also the direction the train is approaching from. She is 500 ft from point Q in the opposite direction of the train's approach. Heather can reach point P at the same time as the train will reach point P while she is running 10mph. She can reach point Q at the same time as the train will reach point Q while she is running 10mph. How fast in mph is the train traveling?
I've tried various d=rt combinations, using the table format, but nothing is correct. I know that the girl can reach point P in 30 units of time or reach point Q in 50 units of time. The train can reach point Q in 50 units of time + the unknown amount of time it takes to reach the bridge. There is an unknown in the distance the train is from the bridge. I think I've looked at this too long.This question is from textbook

Question 116945: A passenger train traveling due west at 40km/h passes a freight train traveling due east at 90km/h. How long after they pass each other will the trains be 325km apart?
My calculation is the distance travelled by both trains are 325 Km.
The time = x.
Therefore,
325 - 40x = 90x
x=2.5 or 2.5 hours, so after 2.5 hours they will be 325 km apart. Is this correct?

Question 117453: I am having troubles completing the following word problem.......
J. Bond and E. Blofeld are driving speedboats in opposite directions after a failed attepmt by the latter to blow up the world with a nuclearbomb. Mr. Bond's boat is going 25 MPH faster than Mr. Blofeld's. After 3 hours they are 500 miles apart. How fast was each of them going?
This is what i have so far but I am stuck
x^2+y^2=500^2
x^2(x^2+25)^2=500^2
x^2+x^2+50x+625=250,000
2x^2+50x+625-625=250,000-625
2x^2+50x-249,375=0
2x^2+50x-249,375=0 divided by 2
x2+25x-124687.50
I am not sure what to do next. Please help. THank you so much!!!
