Question 719872: Piglet and Tigger were walking near the border of the Hundred Acre Woods when they were frightened by a heffalump. Piglet began running to the north at a rate that was 64 feet per minute faster than Tigger began bouncing to the south. When they both stopped four minutes later, the were 1,856 feet apart. How fast did Piglet run? How fast did Tigger bounce?
What is Piglet's and Tigger's rates converted from feet per minute to miles per hour?

Question 719967: A)Treveon paddled 27 miles downstream in his boat. The speed of the water current was 3 mph.
B)Brian paddled 15 miles across the lake in his boat. He was traveling on still water.
C)The total trip took 10 hours.
- Create an equation for each and then solve them
Attempt -
A) 1A: Distance rowed = time to arrive(row speed still water + Current)
step
2A: 27=x(Y+3) assuming x is time and y is row speed (still)
3A: 27=x(8.43+3)
4A: 27=11.43X
5A: X=2.36 same as time to arrive (subtract this from the total of 6.43 hours for how long it took to get back)
B)
1B: Distance Rowed - time(speed)
2B: 15=xy assuming x is time and Y is row speed
3B: 15=3.57/2(y)
4B:15=1.78(Y)
5B: divide both sides by 1.78
5B: y = 8.43 same as speed equals 8.43
C)--Lost--using part over whole method determining the percentage of whole each traveled (wrong method)
I can determine that Treveon of course took 64.3% of the time equaling 6.43 hours and that bryan took 35.7% equaling 3.57 hours. Bryan's would be equally divided since he didn't have to row up stream...
D) How long did it take each to get back?
Brian is 1.79 hours each way
Treveon is 6.43-2.36 there = 4.07 back

Question 720020: On Monday, Amy cycled 24 miles in 2 hours at a constant rate. On Tuesday, she cycled at an average of 3 mph faster. What was her rate on Tuesday?
I tried 24/2= 12
So 24+3=27 and divide by 2 would equal 13.5.
My choices are:
A. 3 mph
B. 15 mph
C. 30 mph
D. 120 mph

Question 720112: This is a word problem from a chapter on Quadratic Equations.
The speed of a boat in still water is 10km/hour. The boat travels upstream 24km and 24km downstream in a total time of 5 hours. What is the speed of the stream?
I know how to solve quadratic equations, so I mainly need to know how to set the problem up, because that's the part that really confuses me.

Question 720308: 2 private airplanes travel toward each other from cities that are 780km apart at speeds of 190km/h and 200km/h . they left at same time. In how many hours will they meet ?
my solution not sure if this is correct
let x = # of hours planes will meet
190x+200x=780km
390x=780
x=2 hours the planes will meet Thank you for checking this for me
